The crash of your thunder was in the whirlwind; your lightnings lighted up the world; the earth trembled and shook.
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 voice of thy thunder was in the heaven, or in the whirlwind. Rushing on with terrific swiftness and bearing all before it, the storm was as a chariot driven furiously, and a voice was heard (even thy voice, O Lord!) out of the fiery car, even as when a mighty man in battle urges forward his charger, and shouts to it aloud.
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.
