Kohen

The Torah mentions Melchizedek king of Salem, identified by Rashi as being Shem the son of Noah, as a priest (kohen) to El Elyon (the supreme God) Genesis 14:18. The second is Potiphera, priest of Heliopolis, then Jethro, priest of Midian both pagan priests of their era.[3]

When Esau sold the birthright of the first born to Jacob, Rashi explains that the priesthood was sold along with it, because by right the priesthood belongs to the first-born. Israel was supposed to become "a kingdom of priests and an holy nation" Exodus 19:6, but when Israel (except the Tribe of Levi) sinned in the incident of the golden calf, Moses broke the tablets containing the higher Exodus 32:19, and then returned up the mountain after making two new tablets Exodus 34:4 to receive commandments which would form the basis of the lesser law which Israel would now have to follow. The lesser priesthood was given to the Tribe of Levi, which had not been tainted by this incident Exodus 32:26[4]

Moses received the priesthood under the hand of his father-in-law, Jethro, after which he spoke to the Lord via the burning bush. As a prophet, (one who speaks with God) he held this higher office within the priesthood. Aaron was ordained as the High Priest of the lesser priesthood or Aaronic Priesthood; which includes the Levitical; to parallel the lesser law the Israelites would now have to follow due to the Golden Calf incident and the subsequent revised covenant. Exodus 34:10.[5]

Moses is referred to as a priest in Psalms 99:6, this refers to his being a prophet, which is an office within the higher Priesthood.

Aaron received the priesthood along with his children and any descendants that would be born subsequently. However, his grandson Phinehas had already been born, and did not receive the priesthood until he killed the prince of the Tribe of Simeon and the princess of the Midianites (Numbers 25:7–13). Thereafter, this lesser priesthood has remained with the descendants of Aaron.

Kohen, Kohen Gadol and a Levite (Charles Foster, 1873)

The Torah provides for specific vestments to be worn by the priests when they are ministering in the Tabernacle: "And you shall make holy garments for Aaron your brother, for dignity and for beauty" (Exodus 28:2). These garments are described in detail in Exodus 28, Exodus 39 and Leviticus 8. The high priest wore eight holy garments (bigdei kodesh). Of these, four were of the same type worn by all priests, and four were unique to the Kohen Gadol.

Those vestments which were common to all priests, were:

• Priestly undergarments (Hebrew michnasayim) (breeches): linen pants reaching from the waist to the knees "to cover their nakedness" (Exodus 28:42)
• Priestly tunic (Hebrew ketonet) (tunic): made of pure linen, covering the entire body from the neck to the feet, with sleeves reaching to the wrists. That of the high priest was embroidered (Exodus 28:39); those of the priests were plain (Exodus 28:40).
• Priestly sash (Hebrew avnet) (sash): that of the high priest was of fine linen with "embroidered work" in blue and purple and scarlet (Exodus 28:39, 39:29); those worn by the priests were of white, twined linen.
• Priestly turban (Hebrew mitznefet): that of the high priest was much larger than that of the priests and wound so that it formed a broad, flat-topped turban; that for priests was wound so that it formed a cone-shaped turban, called a migbahat.

The vestments that were unique to the high priest were:

• Priestly robe (me'il) ("robe of the ephod"): a sleeveless, blue robe, the lower hem of which was fringed with small golden bells alternating with pomegranate-shaped tassels in blue, purple, and scarlet—tekhelet,[6] argaman, tolaat shani.
• Ephod: a richly embroidered vest or apron with two onyx engraved gemstones on the shoulders, on which were engraved the names of the tribes of Israel
• Priestly breastplate (Hebrew hoshen): with twelve gems, each engraved with the name of one of the tribes; a pouch in which he probably carried the Urim and Thummim. It was fastened to the Ephod
• On the front of the turban was a golden plate inscribed with the words: "Holiness unto YHWH" attached to the mitznefet.

The high priest, like all priests, would minister barefoot when he was serving in the Temple. Like all of the priests, he had to immerse himself in the ritual bath before vesting and wash his hands and his feet before performing any sacred act. The Talmud teaches that neither the kohanim nor the Kohen Gadol were fit to minister unless they wore their priestly vestments: "While they are clothed in the priestly garments, they are clothed in the priesthood; but when they are not wearing the garments, the priesthood is not upon them" (B.Zevachim 17:B). It is further taught that just as the sacrifices facilitate an atonement for sin, so do the priestly garments (B.Zevachim 88b). The high priest had two sets of holy garments: the "golden garments" detailed above, and a set of white "linen garments" (bigdei ha-bad) which he wore only on the Day of Atonement (Yom Kippur) (Leviticus 16:4). On that day, he would change his holy garments four times, beginning in the golden garments but changing into the Linen Garments for the two moments when he would enter the Holy of Holies (the first time to offer the blood of atonement and the incense, and the second time to retrieve the censer), and then change back again into the golden garments after each time. He would immerse in the ritual bath before each change of garments, washing his hands and his feet after removing the garments and again before putting the other set on. The linen garments were only four in number, those corresponding to the garments worn by all priests (undergarments, tunic, sash and turban), but made only of white linen, with no embroidery. They could be worn only once, new sets being made each year.

In every generation when the Temple was standing, one kohen would be singled out to perform the functions of the High Priest (Hebrew kohen gadol). His primary task was the Day of Atonement service. Another unique task of the high priest was the offering of a daily meal sacrifice; he also held the prerogative to supersede any priest and offer any offering he chose. Although the Torah retains a procedure to select a High Priest when needed, in the absence of the Temple in Jerusalem, there is no High Priest in Judaism today.

King David assigned each of the 24 priestly clans by lot to a weekly watch (Heb. משמרת, mishmeret) during which its members were responsible for maintaining the schedule of offerings at the Temple in Jerusalem, in accordance with 1 Chronicles 24:3–5. Prior to that time, the priestly courses numbered a mere eight. This newly instated a cycle of priestly courses, or priestly divisions, which repeated itself roughly twice each year.

When the First and Second Temples were built, the priests of Aaron's lineage assumed these roles in the Temple in Jerusalem. Each of the 24 groups consisted of six priestly families, with each of the six serving one day of the week. On the Sabbath day, all six worked in tandem. According to later rabbinical interpretation, these 24 groups changed every Sabbath at the completion of the Mussaf service.. However, on the biblical festivals all 24 were present in the Temple for duty.

According to the Jerusalem Talmud (Ta‘anith 4:2 / 20a): "Four wards came up out of exile: Yedaiah, Harim, Pašḥūr and Immer. The prophets among them had made a stipulation with them, namely, that even if Jehoiariv should come up out of exile, the officiating ward that serves in the Temple at that time should not be rejected on his account, but rather, he is to become secondary unto them."

Although kohanim may assume their duties once they reached physical maturity, the fraternity of kohanim generally would not allow young kohanim to begin service until they reached the age of twenty,[11] and some opinions state that this age was thirty.[12] There was no mandatory retirement age. Only when a kohen became physically infirm could he no longer serve.[13] A kohen may become disqualified from performing his service for a host of reasons, including, but not limited to, Tumah, marital defilements, and physical blemishes. Of importance is that the kohen is never permanently disqualified from service but is permitted to return to his normal duties once the disqualification ceases.

Every Monday, Thursday and Shabbat in Orthodox synagogues (and many Conservative ones as well), a portion from the Torah is read aloud in the original Hebrew in front of the congregation. On weekdays, this reading is divided into three; it is customary to call a kohen for the first reading (aliyah), a Levite for the second reading, and a member of any other Tribe of Israel to the third reading. On Shabbat, the reading is divided into seven portions; a kohen is called for the first aliyah and a levite to the second, and a member of another tribe for the rest.

If a kohen is not present, it is customary in many communities for a levite to take the first aliyah "bimkom kohen" (in the place of a kohen) and an Israelite the second and succeeding ones. This custom is not required by halakha (Jewish law), however, and Israelites may be called up for all aliyot.

In the late 12th and early 13th century, Rabbi Meir of Rothenburg ruled that, in a community consisting entirely of kohanim, the prohibition on calling kohanim for anything but the first two and maftir aliyot creates a deadlock situation which should be resolved by calling women to the Torah for all the intermediate aliyot.

The Conservative Rabbinical Assembly's Committee on Jewish Law and Standards (CJLS), consistent with the Conservative movement's general view of the role of kohanim, has ruled that the practice of calling a kohen to the first aliyah represents a custom rather than a law, and that accordingly, a Conservative rabbi is not obligated to follow it. As such, in some Conservative synagogues, this practice is not followed.

Large crowds congregate on Passover at the Western Wall to receive the priestly blessing

The kohanim participating in an Orthodox and some other styles of traditional Jewish prayer service also deliver the priestly blessing,[17] during the repetition of the Shemoneh Esrei.[18] They perform this service by standing and facing the crowd in the front of the congregation, with their arms held outwards and their hands and fingers in a specific formation, with a Jewish prayer shawl or Talit covering their heads and outstretched hands so that their fingers cannot be seen.[19] Kohanim living in Israel and many Sephardic Jews living in areas outside Israel deliver the priestly blessing daily; Ashkenazi Jews living outside Israel deliver it only on Jewish holidays.[20]

Outside the synagogue, the kohen leads the Pidyon Haben ceremony. This symbolic Redemption of the first-born son is based on the Torah commandment, "and you shall redeem all the firstborn of man among your sons".[21]

Orthodox Judaism recognizes the rules regulating marriage for Jews of priestly stock as being in full force. Rabbinic courts will uphold the laws and will not officiate in a marriage that involves a man who is a Kohen and a Jewish woman who is divorced from an earlier marriage. Areas where Orthodox approaches may create different results include situations where a woman has been raped, kidnapped or held hostage, descendants of converts whose Judaism status turned out to be subject to doubt, ambiguous prior dating histories, and other potentially ambiguous or difficult situations.

A priest of Aaron's lineage (i.e. Kohen) is forbidden by the Mosaic Law (Torah) to marry a divorced woman even if she were a native Israelite. Likewise, a male descendant from Aaron's line is prohibited to marry a Jewish woman who has had intercourse with a non-Jew, whether she had been raped or she had willfully done so. So, too, he cannot marry a Jewish woman whose birth was by a father who is a Kohen but who violated one of these prohibitions. If he went ahead and did one of these three things, his male issue born from such union is no longer a priest (i.e. Kohen), but rather becomes a Ḥallal (Lev. 21:7, 14) - a term designating one who is no longer a priest, but profaned. A priest must maintain an untainted lineage, and his mother must be of Jewish birth. If he married a non-Jewish woman from the gentile nations, his children are no longer priests, but gentiles. Had a priest of Aaron's lineage transgressed this prohibition and married a divorced woman, and they had children together, all of his female issue - whether his, or his sons, or his grandchildren - would be prohibited from marrying into the priestly stock for all generations.[22]

Rape poses an especially poignant problem. The pain experienced by the families of kohanim who were required to divorce their wives as the result of the rapes accompanying the capture of Jerusalem is alluded to in this Mishnah:

If a woman were imprisoned by non-Jews concerning money affairs, she is permitted to her husband, but if for some capital offense, she is forbidden to her husband. If a town were overcome by besieging troops, all women of priestly stock found in it are ineligible [to be married to priests or to remain married to priests], but if they had witnesses, even a slave, or even a bondswoman, these may be believed. But no man may be believed for himself. Rabbi Zechariah ben Hakatsab said, "By this Temple, her hand did not stir from my hand from the time the non-Jews entered Jerusalem until they went out." They said to him: No man may give evidence of himself.[23]

The Israeli rabbinate will not perform a marriage halakhically forbidden to a kohen. For example, a kohen cannot legally marry a divorced or converted woman in the State of Israel, although a foreign marriage would be recognized.

Conservative Judaism has issued an emergency takanah (rabbinical edict) temporarily suspending the application of the rules in their entirety, on the grounds that the high intermarriage rate threatens the survival of Judaism, and hence that any marriage between Jews is welcomed. The takanah declares that the offspring of such marriages are to be regarded as kohanim. The movement allows a kohen to marry a convert or divorcee for these reasons:

• Since the Temple in Jerusalem is no longer extant and korbanot should not be restored, kohanim are no longer able to perform Temple services in a state of ritual purity.
• Because the intermarriage crisis among American Jewry is an extreme situation, the Conservative movement feels it must support the decision of two Jews to marry.[24][25]

Today, Orthodox and many Conservative rabbis maintain the position that only a man can act as a kohen, and that a daughter of a kohen is recognized as a bat kohen only in those very limited ways that have been identified in the past. Other Conservative rabbis, along with some Reform and Reconstructionist rabbis, are prepared to give equal kohen status to the daughter of a kohen.

Orthodox Judaism maintains that the privileges and status of kohanim stem primarily from their offerings and activities in the Temple. Accordingly, in Orthodox Judaism only men can perform the Priestly Blessing and receive the first aliyah during the public Torah reading, and women are generally not permitted to officiate in a Pidyon HaBen ceremony. However, the question of what acts (if any) a bat kohen can perform in an Orthodox context is a subject of current discussion and debate in some Orthodox circles.[26]

Some women's prayer groups that practice under the halakhic guidance of non-Orthodox rabbis, and which conduct Torah readings for women only, have adapted a custom of calling a bat kohen for the first aliyah and a bat levi for the second.[27]

Conservative Judaism, consistent with its view that sacrifices in the Temple will not be restored and in light of many congregations' commitment to gender (but not caste) egalitarianism, interprets the Talmudic relevant passages to permit elimination of most distinctions between male and female kohanim in congregations that retain traditional tribal roles while modifying traditional gender roles. The Conservative movement bases this leniency on the view that the privileges of the kohen come not from offering Temple offerings but solely from lineal sanctity, and that ceremonies like the Priestly Blessing should evolve from their Temple-based origins. (The argument for women's involvement in the Priestly Blessing acknowledges that only male kohanim could perform this ritual in the days of the Temple, but that the ceremony is no longer rooted in Temple practice; its association with the Temple was by rabbinic decree; and rabbis therefore have the authority to permit the practice to evolve from its Temple-based roots).[28] As a result, some Conservative synagogues permit a bat kohen to perform the Priestly Blessing and the Pidyon HaBen ceremony, and to receive the first aliyah during the Torah reading.

The Conservative halakha committee in Israel has ruled that women do not receive such aliyot and cannot validly perform such functions (rabbi Robert Harris, 5748). Therefore, not all Conservative congregations or rabbis permit these roles for bnot kohanim (daughters of priests). Moreover, many egalitarian-oriented Conservative synagogues have abolished traditional tribal roles and do not perform ceremonies involving kohanim (such as the Priestly Blessing or calling a kohen to the first aliyah), and many traditionalist Conservative synagogues have retained traditional gender roles and do not permit women to perform these roles at all.[29]

Because most Reform and Reconstructionist temples have abolished traditional tribal distinctions, roles, and identities on grounds of egalitarianism, a special status for a bat kohen has very little significance in these movements.
