Exodus 23:20-22

“Behold, I am going to send an Angel before you to keep and guard you on the way and to bring you to the place I have prepared. Be on your guard before Him, listen to and obey His voice; do not be rebellious toward Him or provoke Him, for He will not pardon your transgression, since My Name (authority) is in Him. [Ex 32:34; 33:14; Is 63:9] But if you will indeed listen to and truly obey His voice and do everything that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
