(Exodus 21:16) "And one who steals a man and sells him": What is the intent of this? From (Devarim 24:7) "If a man be found (by witnesses) to have stolen a soul of his brothers, etc." I know only of (the necessity for) witnesses to the stealing. Whence do I derive (the same for) witnesses to the selling? From "And one who steals a man and sells him."
