15 With your strong arm you redeemed your people, the descendants of Jacob and Joseph. Selah 16 When the waters saw you, O God, when the waters saw you, they were afraid; the very deep trembled. 17 The clouds poured out water; the skies thundered; your arrows flashed on every side. 18 The crash of your thunder was in the whirlwind; your lightnings lit up the world; the earth trembled and shook. 19 Your way was through the sea, your path, through the mighty waters; yet your footprints were unseen. 20 You led your 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.
