Rashi on Ki Sisa 33:22

English: בעבר כבדי WHEN MY GLORY PASSETH BY – i. e. when I shall pass before you. בנקרת הצור IN A CLEFT OF THE CRAG — נקרה is similar in meaning to the verbs in (Numbers 16:14) “Wilt thou bore out (תנקר) the eyes of these men?”; (Proverbs 30:17) “The ravens of the valley shall pick it out (יקרהו)‎”; (2 Kings 19:24) “I have digged a well (קרתי) and drunk strange waters”. All these have the same derivation. נקרת הצור thus means a place dug out of the rock. ושכתי כפי AND I WILL SHELTER [THEE] WITH MY HAND — Hence it is evident that permission has been given to the destructive agencies to wound. The Targum renders ושכתי כפי by ואגין במימרי “I will protect thee with My word” This is merely a circumlocutio
