Exodus 23:20-22

Complete Jewish Bible

(vi) ²⁰ “I am sending an angel ahead of you to guard you on the way and bring you to the place I have prepared. ²¹ Pay attention to him, listen to what he says and do not rebel against him; because he will not forgive any wrongdoing of yours, since my name resides in him. ²² But if you listen to what he says and do everything I tell you, then I will be an enemy to your enemies and a foe to your foes.
