Deuteronomy 25:1-4

1If there be a controversy between men, and they come unto judgment, and the judges judge them; then they shall justify the righteous, and condemn the wicked. 2And it shall be, if the wicked man be worthy to be beaten, that the judge shall cause him to lie down, and to be beaten before his face, according to his wickedness, by number. 3Forty 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.

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