Deuteronomy 22:18

And the elders of that city shall take the man, and chastise him. Not with words, but blows. Jarchi interprets it of beating, and so does the Talmud F24 T. Bab. Cetubot, fol. 46. 1. ; and both the Targums of Onkelos and Jonathan render it,"shall beat him;'

that is, with the beating or scourging of forty stripes, save one.
