Certainly, that exaltation of the son of Nun took place in order that the leader of those former people might be held eminent among those whom he ruled. But let us see how our Jesus my Lord, leader and ruler of this latter people, is “exalted” in the sight of all the descendants of the sons of Israel. I myself think that he was always exalted and elevated in the presence of the Father. But it is necessary that God exalt him in our sight. He is exalted in my sight when the sublimity and loftiness of his divinity is disclosed to me. When, therefore, is his lofty divinity revealed to me? At that time, assuredly, when I crossed over the Jordan and was equipped with the various defenses of the sacraments for the future battle.
Everyone who is under the law reveres Moses. But when one crosses over to the gospel from the law, by the changed observance the reverence is also changed. It is just as the apostle says, “For I through the law have died to the law so that I may live for God; I was crucified with Christ, but now I live; not I, but Christ lives in me.”
“In that day the Lord exalted Joshua.” The Lord exalted Joshua, for as he increased in age his strength became obvious [for all to see]. They rightly feared the son of Nun with a lawful fear as is fitting for service. And we rightly revere our Jesus with holy fear who stands by us for all eternity.
[AD 253] Origen of Alexandria on Joshua 4:14
