He said, No; but [as] prince of the host of Yahweh am I now come. Joshua fell on his face to the earth, and did worship, and said to him, What says my lord to his servant?
 “And it came to pass, when Joshua was by Jericho, that he lifted up his eyes and looked, and behold, there stood a man over against him with his sword drawn in his hand: and Joshua went unto him, and said unto him, Art thou for us, or for our adversaries? and he said, Nay; but as captain of the host of the Lord am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What saith my lord unto his servant? and the captain of the Lord's host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so.” --Joshua 5:13-15 .
