John Wesley on Joshua 5:14

As captain - I am the chief captain of this people, and will conduct and assist thee and them in this great undertaking. Now this person is not a created angel, but the son of God, who went along with the Israelites in this expedition, as their chief and captain. And this appears, By his acceptance of adoration here, which a created angel durst not admit of, Rev 22:8,9. Because the place was made holy by his presence, Jos 5:15, which was God's prerogative, Exod 3:5. Because he is called the Lord, Heb. Jehovah, Jos 6:2. My Lord - I acknowledge thee for my Lord and captain, and therefore wait for thy commands, which I am ready to obey.
