Deuteronomy 25:5-12 - Preserving The Family Line

⁵ When brothers live together and one of them dies without a son the wife of the deceased shall not marry outside the family to a strange man. Her husband's brother shall marry her and perform the duty of a husband's brother to her. ⁶ The firstborn son she bears will assume the name of the dead brother. That way his name will not be blotted out from Israel. ⁷ If the man does not desire to take his brother's wife, his brother's wife shall go up to the gate to the elders and say: My husband's brother refuses to establish a name for his brother in Israel. He is not willing to perform the duty of a husband's brother to me. ⁸ The elders of his city must summon him and speak to him. If he persists and says: I do not desire to take her, ⁹ his brother's wife shall must to him in the sight of the elders. She will pull his sandal off his foot and spit in his face. Then she will declare: It is done to the man who does not build up his brother's house. ¹⁰ His name in Israel will be: 'The house of him whose sandal is removed.'

¹¹ If two brothers struggle together and the wife of one approaches to help her husband against the other man, and puts out her hand and seizes his genitals, ¹² you must cut off her hand. Do not show pity.
