And if the man desires not to take his brother's wife, then let his brother's wife go up to the gate unto the elders, and say, My husband's brother refuses to raise up unto his brother a name in Israel, he will not perform the duty of my husband's brother.

If brethren dwell together, and one of them dies, and has no child, the wife of the dead shall not marry outside unto a stranger: her husband's brother shall go in unto her, and take her to him as wife, and perform the duty of a husband's brother unto her.
