Deuteronomy 25:3-5

American Standard Version

³ Forty stripes he may give him, he shall not exceed; lest, if he should exceed, and beat him above these with many stripes, then thy brother should seem vile unto thee.

⁴ Thou shalt not muzzle the ox when he treadeth out the grain.

⁵ 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.
