5 The grave wrapped its ropes around me; death laid a trap in my path. 6 But in my distress I cried out to the Lord ; yes, I prayed to my God for help. He heard me from his sanctuary; my cry to him reached his ears. 7 Then the earth quaked and trembled. The foundations of the mountains shook; they quaked because of his anger. 8 Smoke poured from his nostrils; fierce flames leaped from his mouth. Glowing coals blazed forth from him. 9 He opened the heavens and came down; dark storm clouds were beneath his feet. 10 Mounted on a mighty angelic being, he flew, soaring 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.
