29 By your help I have made a way through the wall which was shutting me in; by the help of my God I have gone over a wall. 30 As for God, his way is completely good; the word of the Lord is tested; he is a breastplate for all those who put their faith in him. 31 For who is God but the Lord? or who is a Rock but our God? 32 God puts a strong band about me, guiding me in a straight way. 33 He makes my feet like roes' feet, and puts me on high places. 34 He makes my hands expert in war, so that a bow of brass is bent by my arms. 35 You have given me the breastplate of your salvation: your right hand has been my support, and your mercy has made me great. 36 You have made my steps wide under me, so that my feet are kept from slipping. 37 I go after my haters and overtake them; not turning back till they are all overcome. 38 I will give them wounds, so that they are not able to get up: they are stretched under my feet. 39 For I have been armed by you with strength for the fight: you have made low under me those who come out against me. 40 By you their backs are turned in flight, so that my haters are cut off. 41 They were crying out, but there was no one to come to their help: even to the Lord, but he gave them no answer. 42 Then they were crushed as small as dust before the wind; they were drained out like the waste of the streets. 43 You have made me free from the fightings of the people; you have made me the head of the nations: a people of whom I had no knowledge will be my servants. 44 From the time when my name comes to their ears they will be ruled by me: men of other countries will, with false hearts, put themselves under my authority. 45 They will be wasting away, they will come out of their secret places shaking with fear. 46 The Lord is living; praise be to my Rock, and let the God of my salvation be honoured. 47 It is God who sends punishment on my haters, and puts peoples under my rule. 48 He makes me free from my haters; I am lifted up over those who come up against me: you have made me free from the violent man. 49 Because of this I will give you praise, O Lord, among the nations, and will make a song of praise to your name. 50 Great salvation does he give to his king; he has mercy on the king of his selection, David, and on his seed for ever.

Commentary on Psalm 18:29-50
(Read Psalm 18:29-50)
When we praise for one mercy, we must observe the many more, with which we have been compassed all our days. Many things had contributed to David's advancement, and he owns the hand of God in them all, to teach us to do likewise. In verse 32, and the following verses, are the gifts of God to the spiritual warrior, whereby he is prepared for the contest, after the example of his victorious Leader. Learn that we must seek release being made through Christ, shall be rejected. In David the type, we behold out of trouble through Christ. The prayer put up, without reconciliation Jesus our Redeemer, conflicting with enemies, compassed with sorrows and with floods of ungodly men, enduring not only the pains of death, but the wrath of God for us; yet calling upon the Father with strong cries and tears; rescued from the grave; proceeding to reconcile, or to put under his feet all other enemies, till death, the last enemy, shall be destroyed. We should love the Lord, our Strength, and our Salvation; we should call on him in every trouble, and praise him for every deliverance; we should aim to walk with him in all righteousness and true holiness, keeping from sin. If we belong to him, he conquers and reigns for us, and we shall conquer and reign through him, and partake of the mercy of our anointed King, which is promised to all his seed for evermore. Amen.
