Deuteronomy 25:2-4

New International Version - UK

² If the guilty person deserves to be beaten, the judge shall make them lie down and have them flogged in his presence with the number of lashes the crime deserves, ³ but the judge must not impose more than forty lashes. If the guilty party is flogged more than that, your fellow Israelite will be degraded in your eyes.

⁴ Do not muzzle an ox while it is treading out the grain.
