If brethren dwell together, and one of them die, and have no son, the wife of the dead shall not be married 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 a husband's brother unto her.
These are the statutes and the ordinances which ye shall observe to do in the land which Jehovah, the God of thy fathers, hath given thee to possess it, all the days that ye live upon the earth.
