Joshua 5:13-15 - Commander Of The Lord's Army
13 And Joshua, being near Jericho, 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 one of us or one of our adversaries?
14 And he said, No, but I am the Prince of the host of the LORD; now I am come. Then Joshua falling upon his face in the earth worshipped him and said unto him, What saith my lord unto his slave?
15 And the Prince of the LORD's host said unto Joshua, Loose thy shoes from off thy feet, for the place on which thou dost stand is holy. And Joshua did so.
