15 Thou hast with thine arm redeemed thy people, The sons of Jacob and Joseph. [Selah] 16 The waters saw thee, O God; The waters saw thee, they were afraid: The depths also trembled. 17 The clouds poured out water; The skies sent out a sound: Thine arrows also went abroad. 18 The voice of thy thunder was in the whirlwind; The lightnings lightened the world: The earth trembled and shook. 19 Thy way was in the sea, And thy paths in the great waters, And thy footsteps were not known. 20 Thou leddest thy people like a flock, By the hand of Moses and Aaron.
Matthew Henry's Commentary on Psalm 77:15-20
Commentary on Psalm 77:11-20
(Read Psalm 77:11-20)
The remembrance of the works of God, will be a powerful remedy against distrust of his promise and goodness; for he is God, and changes not. God's way is in the sanctuary. We are sure that God is holy in all his works. God's ways are like the deep waters, which cannot be fathomed; like the way of a ship, which cannot be tracked. God brought Israel out of Egypt. This was typical of the great redemption to be wrought out in the fulness of time, both by price and power. If we have harboured doubtful thoughts, we should, without delay, turn our minds to meditate on that God, who spared not his own Son, but delivered him up for us all, that with him, he might freely give us all things.
