Deuteronomy 25:5-12 - Preserving The Family Line

⁵ When brethren dwell together and one of them die and have no child, the wife of the dead shall not be given out unto a stranger: but her brother-in-law shall go in unto her and take her to wife and marry her. ⁶ And the eldest son which she beareth, shall stand up in the name of his brother which is dead, that his name be not put out in Israel. ⁷ But and if the man will not take his sister-in-law, then let her go to the gate unto the elders and say, 'My brother-in-law refuseth to stir up unto his brother a name in Israel, he will not marry me.' ⁸ Then let the elders of his city call unto him and commune with him. If he stand and say, 'I will not take her,' ⁹ then let his sister-in-law go unto him in the presence of the elders and loose his shoe off his foot and spit in his face and answer and say, 'So shall it be done unto that man that will not build his brother's house.' ¹⁰ And his name shall be called in Israel, the unshoed house.

¹¹ If, when men strive together, one with another, the wife of the one run to, for to rid her husband out of the hands of him that smiteth him and put forth her hand and take him by the privates: ¹² cut off her hand, and let not thine eye pity her.
