Adam Clarke's Bible Commentary Verse 7. Remember not the sins of my youth ] Those which I have committed through inconsiderateness, and heat of passion.
According to thy mercy ] As it is worthy of thy mercy to act according to the measure, the greatness, and general practice of thy mercy; so give me an abundant pardon, a plentiful salvation.
For thy goodness' sake ] Goodness is the nature of God; mercy flows from that goodness.
Matthew Henry Commentary
Verses 1-7 - In worshipping God, we must lift up our souls to him. It is certai that none who, by a believing attendance, wait on God, and, by believing hope, wait for him, shall be ashamed of it. The most advance believer both needs and desires to be taught of God. If we sincerel desire to know our duty, with resolution to do it, we may be sure tha 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, whic 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 ow unworthiness, and satisfied of the riches of God's mercy and grace. Ho boundless is that mercy which covers for ever the sins and follies of youth spent without God and without hope! Blessed be the Lord, the blood of the great Sacrifice can wash away every stain.
