Devarim 8:19-20

Orthodox Jewish Bible

¹⁹ And it shall be, if thou do at all forget Hashem Eloheicha, and walk after acharei elohim, and serve them, and worship them, I testify against you today that ye shall surely perish.

²⁰ As the Goyim which Hashem destroyeth before your face, so shall ye perish; because ye would not be obedient unto the voice of Hashem Eloheichem.
