Deuteronomy 25:3

Forty stripes may be given him, but not more , lest , if one should go on to beat him with more stripes than these, your brother be degraded in your sight .

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.

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