Exodus 23:23 says, “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.” (KJV)

Much of what God did He did it through the ministry of angels. When the children of Israel went into the Promised Land as recorded in the Book of Joshua, they went up against the very first nation or group of people they had to drive out, and it was Jericho . Jericho was
surrounded by a wall so wide that six chariots could race side by side on top of that wall.
                                   
God told Joshua, "I want you to march around that wall once every day for seven days. And on the seventh day I want you to march around it seven times and then blow the trumpet. And those walls will fall down flat." Joshua 6:3-5
                                                           
But how was it that the walls fell down flat? When people obeyed God and did what He said to do, guess who knocked that wall down? The angel that took them into the land to drive out the Amorites, Hittites, and
all the other "-ites" who were there. That land didn't belong to those "-ites", and God sent an angel to fight the battle for the children of Israel .

The Bible tells us that those who were under the Old Covenant don’t have a better covenant than we do under the New Covenant. Whatever they had in the Old Covenant, we have in the New Covenant, plus more And the angels that fought those battles for God's people in the Old Covenant and knocked down walls will fight battles and knock down walls in our covenant too. Heb.8:6

Remember that God said, "I’ll send that angel to go in front of you.  I'll send that angel to be with you. And I’ll send that angel to take you into the place that’s prepared for you, and he will fight for you."

Angels were involved in helping the children of Israel get back what the devil had stolen. And they will do the same for us today.
