Psalms 77:20

"You have led home Your people like sheep in the hand of Moses and of Aaron" [Psalm 77:20]. Why He has added this is somewhat difficult to discover....They banished Christ; sick as they were, they would not have Him for their Saviour; but He began to be among the Gentiles, and among all nations, among many peoples. Nevertheless, a remnant of that people has been saved. The ungrateful multitude has remained without, even the halting breadth of Jacob's thigh. [Genesis 32:32] For the breadth of the thigh is understood of the multitude of lineage, and among the greater part of the Israelites a certain multitude became vain and foolish, so as not to know the steps of Christ on the waters. "You have led home Your people like sheep," and they have not known You. Though You have done such great benefits unto them, hast divided sea, hast made them pass over dry land between waters, hast drowned in the waves pursuing enemies, in the desert hast rained manna for their hunger, leading them home "by the hand of Moses and Aaron:" still they thrust You from them, so that in the sea was Your Way, and Your steps they knew not.

And your footsteps shall not be known: you led out your people like sheep. The good shepherd led out his people like sheep. By the hand of Moses and Aaron. This he did according to the letter: for the rest, daily he does it in us. By the hand of Moses, that is, in the law (and we know that the law is spiritual): in the spiritual law. And of Aaron: that is, in the priesthood. In your spiritual law, and in your spiritual priesthood, you led out your people. Let us understand this according to the letter of Moses and Aaron. Moses indeed was led out, and Aaron, but not led into the land of promise. Jesus succeeded him. See what is written. Moses died in the desert, Aaron died, Miriam died; and this is what is written in the prophet: "And I will strike," it says, "three shepherds in one month." They died: for they could not enter into the land of promise. They only saw over against the land of promise, and could not enter. The Jews saw the land of promise, and could not enter. For they died in the desert, and their corpses are in the wilderness, of those who died in the desert. We, the sons, under Jesus as leader, came to the Jordan, and entered into the land of promise, and came to Gilgal, and were a second time circumcised with a spiritual circumcision, and the reproach of Egypt was taken away from us. Then Jesus himself our leader holds the sword, and always goes before us, and fights for us, and conquers our adversaries, and for seven days we go around Jericho, that is, this world. We sing with the priestly trumpets, and we go around Jericho, that is, this world, and its walls fall, and we enter in, and we are the victors. Then we conquer the city of Ai: afterward we come to Jebus, we come to Hazor, we come to other cities; we conquer the adversaries whom under Moses we could not conquer. Let us give thanks, then, to our leader Jesus: for with him as leader, with him fighting, we conquer. He commanded the sun to stand still, and it stood still, and that great man was a type of this one: he was commanding, but the Lord was accomplishing it. He came forth the victor: he, as I have often said, slew five kings in the cave: he led us into the land of promise. To him let us give thanks; he is the son of Nun, which we read as Nave: he it is who was called Osee, which we read as Ause. For according to the Hebrew truth it is not said Ause, but Osee, that is,…
