Deuteronomy 25:1-3

¹“If there is a dispute between men and they go to court, and the judges decide their case, and they justify the righteous and condemn the wicked, ²then it shall be if the wicked man deserves to be beaten, the judge shall then make him lie down and be beaten in his presence with the number of stripes according to his guilt. ³He may beat him forty times but no more, so that he does not beat him with many more stripes than these and your brother is not degraded in your eyes.
