7 Then the earth shook and trembled; The foundations also of the mountains quaked And were shaken, because he was wroth. 8 There went up a smoke out of his nostrils, And fire out of his mouth devoured: Coals were kindled by it. 9 He bowed the heavens also, and came down; And thick darkness was under his feet. 10 And he rode upon a cherub, and did fly; Yea, he soared upon the wings of the wind. 11 He made darkness his hiding-place, his pavilion round about him, Darkness of waters, thick clouds of the skies. 12 At the brightness before him his thick clouds passed, Hailstones and coals of fire. 13 Jehovah also thundered in the heavens, And the Most High uttered his voice, Hailstones and coals of fire. 14 And he sent out his arrows, and scattered them; Yea, lightnings manifold, and discomfited them. 15 Then the channels of waters appeared, And the foundations of the world were laid bare, At thy rebuke, O Jehovah, At the blast of the breath of thy nostrils.
Matthew Henry's Commentary on Psalm 18:7-15
Commentary on Psalm 18:1-19
(Read Psalm 18:1-19)
The first words, "I will love thee, O Lord, my strength," are the scope and contents of the psalm. Those that truly love God, may triumph in him as their Rock and Refuge, and may with confidence call upon him. It is good for us to observe all the circumstances of a mercy which magnify the power of God and his goodness to us in it. David was a praying man, and God was found a prayer-hearing God. If we pray as he did, we shall speed as he did. God's manifestation of his presence is very fully described, Hebrews 5:7. God made the earth to shake and tremble, and the rocks to cleave, and brought him out, in his resurrection, because he delighted in him and in his undertaking.
