Q. Can you explain to me Psalm 77:16, 19? How are we to interpret these verses?
Let’s read the passage and it’s context:
11* ¶ I shall remember the deeds of the LORD; Surely I will remember Your wonders of old.
12* I will meditate on all Your work And muse on Your deeds.
13* Your way, O God, is holy; What god is great like our God?
14* You are the God who works wonders; You have made known Your strength among the peoples.
15* You have by Your power redeemed Your people, The sons of Jacob and Joseph. Selah.
16* The waters saw You, O God; The waters saw You, they were in anguish; The deeps also trembled.
17* The clouds poured out water; The skies gave forth a sound; Your arrows flashed here and there.
18* The sound of Your thunder was in the whirlwind; The lightnings lit up the world; The earth trembled and shook.
19* Your way was in the sea And Your paths in the mighty waters, And Your footprints may not be known.
20* You led Your people like a flock By the hand of Moses and Aaron.
The Psalmist is describing the crossing of the Red Sea as Moses lead the children of Israel out of Egyptian captivity (Exodus 14:21ff). This section should be understood poetically.
This is a description of God’s mighty power not only over the Egyptian army but also over the forces of nature. God made nature to be on the side of the Israelites and against the Egyptians.
The statement in verse 19 simply means that God’s ways are unknowable. When a ship passes though the seas it leaves no footprints, no evidence that it has been there. The way God works in this world is also unknowable.
