Joshua 5:13

And it came to pass, when Joshua was by Jericho, while the children of Israel were in camp at Gilgal, Joshua, apparently, being engaged in deep meditation and prayer to Jehovah, that he lifted up his eyes and looked, and, behold, there stood a man over against him with His sword drawn in His hand, taken from the scabbard and ready for slaughter. That was the Prince of the host of angels, the great Angel of the Lord, the Angel of the Covenant, of one essence with the Lord Himself, who had accompanied Israel from Egypt and from Sinai. And Joshua went unto Him and said unto Him, Art Thou for us or for our adversaries? It was a question natural in the circumstances and appropriate for the general of the forces of Israel.
