Deuteronomy 25:5-7

DouayRheims(i) 5 When brethren dwell together, and one of them dieth without children, the wife of the deceased shall not marry to another: but his brother shall take her, and raise up seed for his brother: 6 And the first son he shall have of her he shall call by his name, that his name be not abolished out of Israel. 7 But if he will not take his brother's wife, who by law belongeth to him, the woman shall go to the gate of the city, and call upon the ancients, and say: My husband's brother refuseth to raise up his brother's name in Israel: and will not take me to wife.
