6 In my distress I called upon the Lord; to my God I cried for help. From his temple he heard my voice, and my cry to him reached his ears. 7 Then the earth reeled and rocked; the foundations also of the mountains trembled and quaked, because he was angry. 8 Smoke went up from his nostrils,[1] and devouring fire from his mouth; glowing coals flamed forth from him. 9 He bowed the heavens and came down; thick darkness was under his feet. 10 He rode on a cherub and flew; he came swiftly on the wings of the wind. 11 He made darkness his covering, his canopy around him, thick clouds dark with water. 12 Out of the brightness before him hailstones and coals of fire broke through his clouds. 13 The Lord 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; he flashed forth lightnings and routed them. 15 Then the channels of the sea were seen, and the foundations of the world were laid bare at your rebuke, O Lord, at the blast of the breath of your nostrils. 16 He sent from on high, he took me; he drew me out of many waters. 17 He rescued me from my strong enemy and from those who hated me, for they were too mighty for me. 18 They confronted me in the day of my calamity, but the Lord was my support. 19 He brought me out into a broad place; he rescued me, because he delighted in me.

Matthew Henry's Commentary on Psalm 18:6-19

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.
