7 Then the earth shook and trembled; The foundations of the hills also quaked and were shaken, Because He was angry. 8 Smoke went up from His nostrils, And devouring fire from His mouth; Coals were kindled by it. 9 He bowed the heavens also, and came down With darkness under His feet. 10 And He rode upon a cherub, and flew; He flew upon the wings of the wind. 11 He made darkness His secret place; His canopy around Him was dark waters And thick clouds of the skies. 12 From the brightness before Him, His thick clouds passed with hailstones and coals of fire. 13 The Lord thundered from heaven, And the Most High uttered His voice, Hailstones and coals of fire. 14 He sent out His arrows and scattered the foe, Lightnings in abundance, and He vanquished them. 15 Then the channels of the sea were seen, The foundations of the world were uncovered At Your rebuke, O Lord, At the blast of the breath of Your 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.
