And Joshua fell on his face to the earth, AND DID WORSHIP, and said unto him, What saith my lord unto his servant?
Josh 5:15 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.
The Captain of the Host was preincarnate Jesus Christ.
