(18) Prevented.--Better, fell upon me unawares. See this use of the verb, generally however used in a good sense, in Psalm 18:5.

Verse 18. - They prevented me in the day of my calamity (comp. 1 Samuel 23:13-15; 1 Samuel 24:1-3; 1 Samuel 26:1-4, etc.). But the Lord was my Stay. God frustrated all the designs of David's foes, and prevented him from falling into their hands.

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, ver. 7-15. Little appeared of man, but much of God, in these deliverances. It is not possible to apply to the history of the son of Jesse those awful, majestic, and stupendous words which are used through this description of the Divine manifestation. Every part of so solemn a scene of terrors tells us, a greater than David is here. God will not only deliver his people out of their troubles in due time, but he will bear them up under their troubles in the mean time. Can we meditate on ver. 18, without directing one thought to Gethsemane and Calvary? Can we forget that it was in the hour of Christ's deepest calamity, when Judas betrayed, when his friends forsook, when the multitude derided him, and the smiles of his Father's love were withheld, that the powers of darkness prevented him? The sorrows of death surrounded him, in his distress he prayed, Heb 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.They prevented me in the day of my calamity,.... Referring to the times of his distress in the garden and upon the cross; the time of his sufferings and death, which was a dark and cloudy day, as the word (x) used suggests, both in a literal and in a spiritual sense; and when the day and hour was come, fixed and determined by the will of God, then his enemies, though not before, met him, laid hold on him, were too mighty for him, condemned, crucified, and insulted him;

but the Lord was my stay; or staff, on whom he leaned, relied, and depended, believing he would help him; and by whom he was supported and upheld, Isaiah 42:1. The Targum is,

"the Word of the Lord was my stay.''
