52 But made his own people to go forth like sheep, and guided them in the wilderness like a flock.
[AD 379] Basil of Caesarea on Psalms 78:47-66
The Spirit speaks with the authority of the Lord: “The Spirit said to [Peter], ‘Rise and go down, and accompany them without hesitation; for I have sent them.’ ” Are these the words of an abject inferior? “Set apart for me Barnabas and Saul for the work to which I have called them.” Does a slave give commands like this? Isaiah says, “The Lord God and his Spirit have sent me,” and “the Spirit came down from the Lord and led them.” Do not try again to convince me that this “leading” by the Spirit is some lowly service. Scripture testifies that it is the work of God: “He led forth his people like sheep,” it says, and “You who lead Joseph like a flock,” and “He led them in safety so that they were not afraid.” Therefore, when you hear that “the Comforter will bring to remembrance all that I have said to you and will guide you into all truth,” do not quibble over the meaning.

[AD 458] Theodoret of Cyrus on Psalms 78:47-66
The blessed David fell into several errors, which God, who wisely orders all things, has caused to be recorded for the good of them that were to come after. But it was not on their account that Absalom, parricide, murderer, impious and altogether vile, started his wild war against his father. The reason of his beginning that most unrighteous struggle was because he coveted the sovereignty. The divine David, however, when these events were coming to pass, began to remember the wrong that he had done. I too am conscious within myself of the guilt of many errors, but I have kept undefiled the dogmatic teaching of the apostles. And they who have trampled on all laws human and divine and condemned me in my absence have not sentenced me for what I have done wrong, for my secret deeds are not made manifest to them; but they have contrived false witness and false charges against me, or rather in their open attack on the doctrines of the apostles have proscribed me for my obedience to them. “So the Lord awoke as one out of sleep; he put his enemies to rout and put them to everlasting disgrace.” Counterfeit and spurious doctrines he has scattered to the winds, and he has provided for the free preaching of those which he has handed down to us in the holy Gospels. To me this suffices for complete delight. I do not even long for a city in which I have passed all my time in hard work; all I long for is to see the establishment of the truth of the Gospels. And now the Lord has satisfied this longing. I am therefore very glad and happy, and I sing praises to our generous Lord, and I invite your honor to rejoice with me, and, with our praises, to put up the earnest prayer that the people who say now one thing and now another and change about to suit the hour, like the chameleons who assume the color of the leaves, may be strengthened by the loving-kindness of the Lord, established on the rocks and, of his mercy, made to pay the highest honor to the truth.

[AD 430] Augustine of Hippo on Psalms 78:51-53
The Psalm proceeds then after the commemoration of the plagues of the Egyptians [Psalm 78:51] and says, "And He took away like sheep His people, and He led them through like a flock in the desert" [Psalm 78:52]. "And He led them down in hope, and they feared not, and their enemies the sea covered" [Psalm 78:53]. This comes to pass to so much the greater good, as it is a more inward thing, wherein being delivered from the power of darkness, we are in mind translated into the Kingdom of God, and with respect to spiritual pastures we are made to become sheep of God, walking in this world as it were in a desert, inasmuch as to no one is our faith observable: whence says the Apostle, "Your life is hidden with Christ in God." [Colossians 3:3] But we are being led home in hope, "For by hope we are saved." [Romans 8:24] Nor ought we to fear. For, "If God be for us, who can be against us?" [Romans 8:31] And our enemies the sea has covered, He has effaced them in baptism by the remission of sins.
