And that prophet or that dreamer of a dream shall be put to death, for he has spoken falsity against Hashem your God Who brought you out of the land of Egypt and Who redeemed you from the house of bondage, to make you stray from the way that Hashem your God commanded you to walk in; and you shall purge the evil from your midst.
English: “To make you stray” — The Sages taught: A prophet who led astray is put to death by stoning. What is the reason? We derive “leading astray” from “leading astray” of the mesis: just as the mesis is stoned, so too a prophet who led astray is stoned.
On the daf / in context: Although a generic death penalty is usually strangulation, the verbal analogy to the mesis establishes stoning for the false prophet who incites.
