레위기 21:14 할라카: Mishneh Torah, Marriage, Mishneh Torah, Negative Mitzvot & Sefer HaChinukh

Intercourse prohibitions according to the Torah for which there is no punishment of karet are called “negative prohibitions”. They are also called “holy prohibitions”. There are nine [such prohibitions] and they are: a widow to a high priest, a divorced woman or zona or ḥalala to a high priest or to an ordinary priest, a mamzeret to an Israelite man, an Israelite woman to a mamzer, an Israelite woman to an Ammonite or Moabite man, an Israelite woman to one with crushed [genitals], or severed [genitals], one’s ex-wife after she has remarried, one’s yevama who married a stranger while still under the yavam’s control. A ḥalutza is like a divorced woman and is forbidden to a priest according to Rabbinic law. The Gibeonites are like mamzerim, whether male or female, and they are prohibited according to Rabbinic law. The Gibeonites will be explained in the Laws of Forbidden Intercourse.

That the High Priest shall not take a widow in marriage, as it is said, “A widow, or a divorced woman, or profane, or a harlot (these shall he not take)” (Lev. 21:14).

That the priest shall not leave the Courtyard of the Sanctuary, during service, as it is said, “And ye shall not go out from the door of the tent of the congregation, lest ye die” (Lev. 10:7).
