Deuteronomy 25:4-5
4
Thou shalt not muzzle the ox when he treadeth out the corn.
5
¶ If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her.
