n°6 / Joshua 5 :

14And 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 ?
15And 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.
