181 I will give you my love, O Lord, my strength. 2 The Lord is my Rock, my walled town, and my saviour; my God, my Rock, in him will I put my faith; my breastplate, and the horn of my salvation, and my high tower. 3 I will send up my cry to the Lord, who is to be praised; so will I be made safe from those who are against me. 4 The cords of death were round me, and the seas of evil put me in fear. 5 The cords of hell were round me: the nets of death came on me. 6 In my trouble my voice went up to the Lord, and my cry to my God: my voice came to his hearing in his holy Temple, and my prayer came before him, even into his ears.

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.
