181 To the choirmaster. A Psalm of David the servant of the Lord, who addressed the words of this song to the Lord on the day when the Lord delivered him from the hand of all his enemies, and from the hand of Saul. He said: I love thee, O Lord, my strength. 2 The Lord is my rock, and my fortress, and my deliverer, my God, my rock, in whom I take refuge, my shield, and the horn of my salvation, my stronghold. 3 I call upon the Lord, who is worthy to be praised, and I am saved from my enemies.
Matthew Henry's Commentary on Psalm 18:1-3
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.
