Tehillim 106:33-35

Orthodox Jewish Bible

³³ Because they provoked His Ruach [Hakodesh] and he [Moshe] spoke unadvisedly with his sfatayim (lips).

³⁴ They did not destroy the amim (peoples), as Hashem commanded them;

³⁵ But they mingled with the Goyim, and learned their ma’asim (works, customs).
