Tehillim 106:31-33

Orthodox Jewish Bible

³¹ And that was counted unto him for tzedakah l’dor vador ad olam.

³² They angered Him also at the waters of Merivah, so that it went ill with Moshe on their account;

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