Joshua 5:13-15 - Commander Of The Lord's Army
13 And it came to pass, when Joshua was by Jericho, that he lifted up his eyes and looked, and, behold, there stood a man opposite him with his sword drawn in his hand: and Joshua went unto him, and said unto him, are you for us, or for our adversaries?
14 And he said, Nay; but as captain of the army of the LORD am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What says my lord unto his servant?
15 And the captain of the LORD'S army said unto Joshua, Loose your shoes from off your feet; for the place on which you stand is holy. And Joshua did so.
