'Prince' in the Bible

And He saith, 'No, for I am Prince of Jehovah's host; now I have come;' and Joshua falleth on his face to the earth, and doth obeisance, and saith to Him, 'What is my Lord speaking unto His servant?'

And the Prince of Jehovah's host saith unto Joshua, 'Cast off thy shoe from off thy foot, for the place on which thou art standing is holy;' and Joshua doth so;

And with him ten princes, of each chief house a prince throughout all the tribes of Israel; and each one was an head of the house of their fathers among the thousands of Israel.
