Joshua 5:14

14.And he said, Nay; but as captain, etc Although the denial applies equally to both parts of the question, namely, that he was neither an Israelite nor a Canaanite, and was thus equivalent to a denial of his being a mortal man, yet it seems to be more properly applicable to the second, or to that part of the question in which Joshua asked if he were one of the enemy. This, however, is a matter of little moment; the essential thing is to understand that he had come to preside over the chosen people whom he honorably styles the Lord’s host. In his representing himself as different from God, a personal distinction is denoted, but unity of essence is not destroyed.

We have said that in the books of Moses the name of Jehovah (58) is often attributed to the presiding Angel, who was undoubtedly the only-begotten Son of God. He is indeed very God, and yet in the person of Mediator by dispensation, he is inferior to God. I willingly receive what ancient writers teach on this subject, — that when Christ anciently appeared in human form, it was a prelude to the mystery which was afterwards exhibited when God was manifested in the flesh. We must beware, however, of imagining that Christ at that time became incarnate, since, first, we nowhere read that God sent his Son in the flesh before the fullness of the times; and, secondly, Christ, in so far as he was a man, behooved to be the Son of David. But as is said in Ezekiel, (Ezekiel 1:0) it was only a likeness of man. Whether it was a substantial body or an outward form, it is needless to discuss, as it seems wrong to insist on any particular view of the subject. (59)

The only remaining question is, how the Captain of the Lord’s host can speak of having now come, seeing he had not deserted the people committed to his trust, and had lately given a matchless display of his presence in the passage of the Jordan. But according to the common usage of Scripture, God is said to come to us when we are actually made sensible of his assistance, which seems remote when not manifested by experience. It is therefore just as if he were offering his assistance in the combats which were about to be waged, and promising by his arrival that the war would have a happy issue. It cannot be inferred with certainty from the worship which he offered, whether Joshua paid divine honor to Christ distinctly recognized as such; but by asking, What command does my Lord give to his servant? he attributes to him a power and authority which belong to God alone.
