Deḇarim (Deuteronomy) 13:5

“And that prophet or that dreamer of dreams is put to death, because he has spoken apostasy against יהוה your Elohim – who brought you out of the land of Mitsrayim and ransomed you from the house of bondage – to make you stray from the way in which יהוה your Elohim commanded you to walk. Thus you shall purge the evil from your midst.
