7 Earth wobbles and lurches; huge mountains shake like leaves, Quake like aspen leaves because of his rage. 8 His nostrils flare, bellowing smoke; his mouth spits fire. Tongues of fire dart in and out; 9 he lowers the sky. He steps down; under his feet an abyss opens up. 10 He's riding a winged creature, swift on wind-wings. 11 Now he's wrapped himself in a trenchcoat of black-cloud darkness. 12 But his cloud-brightness bursts through, spraying hailstones and fireballs. 13 Then God thundered out of heaven; the High God gave a great shout, spraying hailstones and fireballs. 14 God shoots his arrows - pandemonium! He hurls his lightnings - a rout! 15 The secret sources of ocean are exposed, the hidden depths of earth lie uncovered The moment you roar in protest, let loose your hurricane anger.
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.
