It happened, when Joshua was by Jericho, that he 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 to him, and said to him, Are you for us, or for our adversaries?
The former view, however, is the more correct, as God does not produce anything of an unwonted nature, but constitutes that which we previously read that he performed to Moses. And we know that Moses himself preferred this favor to all others; and justly, for God there manifested his own glory in an open and familiar manner. Accordingly, he is indiscriminately called an angel, and distinguished by the title of the eternal God. Of this fact Paul is a competent witness, who distinctly declares that it was Christ. (1 Corinthians 10:4.) And Moses himself embraced God as present in the person of the Mediator. For when God declares, after the making of the calf, (Exodus 33:2 (56)) that he would no longer be the Leader of the people, he at the same time promises that he will give one of his angels, but only one, as it were taken out of the general body of the angelic host. (57) This Moses earnestly deprecates, obviously because he could have no hope that God would be propitious if the Mediator were removed. It was thus a special pledge of the divine favor that the Captain and Head of the Church, to whom Moses had been accustomed, was now present to assist. And indeed the divine adoption could not be ratified in any other way than in the hand of the Mediator.
