Exodus 23:20-22
The Angel of the Presence
23:20 “I am going to send an angel before you to protect you as you journey and to bring you into the place that I have prepared.
23:21 Take heed because of him, and obey his voice; do not rebel against him, for he will not pardon your transgressions, for my name is in him.
23:22 But if you diligently obey him and do all that I command, then I will be an enemy to your enemies, and I will be an adversary to your adversaries.
