The High Priest Marrying a Widow

"A widow... he not marry"Leviticus 21:14.

A High Priest is forbidden to marry a widow.

(Actually, it is forbidden for a High Priest to have sexual relations with a widow—even without marriage. Thus, if he marries a widow and has relations with her, he transgresses two prohibitions.)

A priest may not marry a chalalah [a woman who in the past had sexual relations with a priest whom she is forbidden to marry because of his priestly status (e.g., she was a divorcee)], or the daughter born from a relationship between a priest and a chalalah.
