Joshua:5:13-6
akjv@Joshua:5:13 @ And it came to pass, when Joshua was by Jericho, that he lifted up his eyes and looked, and, behold, there stood a man over against him with his sword drawn in his hand: and Joshua went to him, and said to him, Are you for us, or for our adversaries?
akjv@Joshua:5:14 @ And he said, No; 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 to him, What said my Lord to his servant?
akjv@Joshua:5:15 @ And the captain of the LORD' host said to Joshua, Loose your shoe from off your foot; for the place where on you stand is holy. And Joshua did so.
