Joshua 5
13 Ref Now when Joshua was near Jericho, lifting up his eyes he saw a man in front of him, with his sword uncovered in his hand: and Joshua went up to him and said, Are you for us or against us?
14 Ref And he said, No; but I have come as captain of the armies of the Lord. Then Joshua, falling down with his face to the earth in worship, said, What has my lord to say to his servant?
15 Ref And the captain of the Lord's army said to Joshua, Take off your shoes from your feet, for the place where you are is holy. And Joshua did so.
