Deuteronomy 25:3

3 And they shall scourge him with forty stripes in number, they shall not inflict more; for if thou shouldest scourge him more stripes beyond these stripes, thy brother will be disgraced before thee.

Deuteronomy 25:3 In-Context

1 And if there should be a dispute between men, and they should come forward to judgment, and judge, and justify the righteous, and condemn the wicked:
2 then it shall come to pass, if the unrighteous should be worthy of stripes, thou shalt lay him down before the judges, and they shall scourge him before them according to his iniquity.
3 And they shall scourge him with forty stripes in number, they shall not inflict more; for if thou shouldest scourge him more stripes beyond these stripes, thy brother will be disgraced before thee.
4 Thou shalt not muzzle the ox that treads out the corn.
5 And if brethren should live together, and one of them should die, and should not have seed, the wife of the deceased shall not marry out to a man not related: her husband's brother shall go in to her, and shall take her to himself for a wife, and shall dwell with her.
