Deuteronômio 22:18 Comentário: Rashi, Chizkuni, Siftei Chakhamim & Rav Hirsch

ויסרו אתו [AND THE ELDERS … SHALL TAKE THE MAN] AND CHASTISE HIM — i.e. with lashes (Sifrei Devarim 238:2; Ketubot 46a; cf. Onkelos).

ויסרו אותו, “they will chastise him;” they will administer punitive lashes to his skin for having transgressed the positive commandment that “you shall love your neighbour as if he were yourself.” (Leviticus 19,18)

Flogging. Because we learn “and chastise” from “and chastise” and “son” from “son.” It is written here “and they shall ויסרו (chastise him),” and by the wayward and rebellious son it is written (above 21:18) “and they shall ויסרו (chastise him).” Just as over there it means flogging, so too here it means flogging. And from where do we know [that it means flogging] over there? Because by the wayward and rebellious son it is written “בן (son),” and by flogging (below 25:2) it is written, “Should the wicked one (בן) deserve flogging, etc.” And we learn “son” from “son” as I explained.
