The waters saw You, O God; the waters saw You and swirled; even the depths were shaken.
PSALM 77 Whoever was the penman of this psalm, the Holy Spirit seems, by his mouth, to have dictated a common form of prayer for the Church in her afflictions, that even under the most cruel persecutions the faithful might not fail to address their prayers to heaven.
Commenting on Psalm 77:1-20
The waters saw thee, O God, the waters saw thee; they were afraid. As if conscious of its Maker's presence, the sea was ready to flee from before his face. The conception is highly poetical, the psalmist has the scene before his mind's eye, and describes it gloriously.
The psalmist here recovers himself out of the great distress and plague he was in, and silences his own fears of God's casting off his people by the remembrance of the great things he had done for them formerly, which though he had in vain tried to quiet himself with (Psa 77:5, Psa 77:6) yet he tried again, and, upon this second trial, found it not in vain.
