Deuteronomy 25:4-6

21st Century King James Version

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 outside unto a stranger; her husband’s brother shall go in unto her, and take her to him for a wife, and perform the duty of a husband’s brother unto her.

⁶ And it shall be that the firstborn whom she beareth shall succeed in the name of his brother who is dead, that his name be not put out of Israel.
