You led your people like a flock by the hand of Moses and Aaron.
All Commentaries on Psalms 77:20 Go To Psalms 77
Augustine of Hippo
AD 430
20. "Thou hast led home Thy people like sheep in the hand of Moses and of Aaron" (ver. 20). Why He hath 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 hath been saved. The ungrateful multitude hath remained without, even the halting breadth of Jacob's thigh. 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. "Thou hast led home Thy people like sheep," and they have not known Thee. Though Thou hast 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 Thee from them, so that in the sea was Thy Way, and Thy steps they knew not.
