开脱礼(ייבום וחליצה)是希伯来圣经规定了一种夫兄弟婚的婚姻制度。当一个男子死亡，这位寡妇必须嫁给他的兄弟之一。但行过开脱礼后，这个嫂子可以自由选择配偶，而不用嫁给丈夫的兄弟。

Under the Biblical system of levirate marriage known as Yibbum, Halizah (or Chalitzah ; Hebrew:חליצה‎) is the process by which a widow and her husband's brother would avoid the duty to marry after the husband's death.

The process involves the taking off of a brother-in-law's shoe by the widow of a brother who has died childless, through which ceremony he is released from the obligation of marrying her, and she becomes free to marry whomever she desires (Deuteronomy25:5-10).
