Moses wrote down this law and gave it to the priests, the sons of Levi, who carried the ark of the Lord’s covenant, and to all the elders of Israel.

“When brothers live on the same property and one of them dies without a son, the wife of the dead man may not marry a stranger outside the family. Her brother-in-law is to take her as his wife, have sexual relations with her, and perform the duty of a brother-in-law for her.

But if the man doesn’t want to marry his sister-in-law, she must go to the elders at the city gate and say, ‘My brother-in-law refuses to preserve his brother’s name in Israel. He isn’t willing to perform the duty of a brother-in-law for me.’

Do not intermarry with them. Do not give your daughters to their sons or take their daughters for your sons,
