I was paraphrasing to make my point that God doesn’t send Himself. Rather, He sends the angel as Himself, to do the work He is doing.
Exo 23:20 - Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared.
Exo 23:23 - For mine Angel shall go before thee, and bring thee in unto the Amorites, and the Hittites, and the Perizzites, and the Canaanites, the Hivites, and the Jebusites: and I will cut them off.
Exo 33:2 - And I will send an angel before thee; and I will drive out the Canaanite, the Amorite, and the Hittite, and the Perizzite, the Hivite, and the Jebusite:
Exo 33:3
Unto a land flowing with milk and honey: for I will not go up in the midst of thee; for thou
art a stiffnecked people: lest I consume thee in the way.
Exo 32:34 - Therefore now go, lead the people unto
the place of which I have spoken unto thee: behold, mine Angel shall go before thee: nevertheless in the day when I visit I will visit their sin upon them.
God was sending His angel to bring the people into the land. God Himself was not going because He would consume them in the way because of their stiffnecks.
Do you see that? God sends His angel and says that it is He Himself (God) doing the work. But He didn’t go Himself, He sent an angel to do HIS work.
