After the garden of Eden and the angels, there is another story in Exodus 23:20, about another angel.
This angel goes ahead as a battle is about to happen. In those days it was even more likely for people to see an angel, as they were given instructions.
“Behold, I send an angel before you to guard you on the way and to bring you to the place that I have prepared. Pay careful attention to him and obey his voice; do not rebel against him, for he will not pardon your transgression, for my name is in him.
But if you carefully obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
When my angel goes before you and brings you to the Amorites and the Hittites and the Perizzites and the Canaanites, the Hivites and the Jebusites, and I blot them out, you shall not bow down to their gods nor serve them, nor do as they do, but you shall utterly overthrow them and break their pillars in pieces. You shall serve the LORD your God, and He will bless your bread and your water, and I will take sickness away from among you.
This goes through verse 25, and as Canaan is about to fall the instruction is given to listen to the angel. It would be wise to listen in the battle, God fights for us when we are still, and this tie in perfectly with listening to voice of the Spirit and to our Father, for Jesus made it possible for us to come and ask in His name.
