Verse 2.- O my God, I trust in thee (comp. Psalm 7:1; Psalm 11:1; Psalm 31. I, 6, etc

25:1-7 In worshipping God, we must lift up our souls to him. It is certain that none who, by a believing attendance, wait on God, and, by a believing hope, wait for him, shall be ashamed of it. The most advanced believer both needs and desires to be taught of God. If we sincerely desire to know our duty, with resolution to do it, we may be sure that God will direct us in it. The psalmist is earnest for the pardon of his sins. When God pardons sin, he is said to remember it no more, which denotes full remission. It is God's goodness, and not ours, his mercy, and not our merit, that must be our plea for the pardon of sin, and all the good we need. This plea we must rely upon, feeling our own unworthiness, and satisfied of the riches of God's mercy and grace. How boundless is that mercy which covers for ever the sins and follies of a youth spent without God and without hope! Blessed be the Lord, the blood of the great Sacrifice can wash away every stain.O my God, I trust in thee,.... He claims his interest in God, and expresses his faith and confidence in him, in the midst of all his troubles; See Gill on Psalm 7:1;

let me not be ashamed; meaning of his trust in God, by being disappointed of the help, deliverance, and salvation from him, which he trusted in him for; and the believer, as he has no reason to be ashamed of God, the object of his trust; so neither of the act of his hope or trust in him; nor shall he; for hope makes not ashamed; see Psalm 119:116, Romans 5:5;

let not mine enemies triumph over me; either his temporal enemies, his subjects that were risen up against him; or his spiritual enemies, Satan, and the men of the world, who rejoice and triumph when the saints are forsaken by God; and they are ready to say, as David's enemies did of him, there is no help or salvation for him in God, Psalm 3:2; and when they fall into their hands, or fall by them.
