5 the cords of Sheol entangled me; the snares of death confronted me. 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.
Matthew Henry's Commentary on Psalm 18:5-10
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.
