Matthew Henry Commentary Psalms 19:11-14

"Moreover by them is thy servant warned: In keeping them there is great reward. Who can discern [his] errors? Clear thou me from hidden [faults]. Keep back thy servant also from presumptuous [sins]; Let them not have dominion over me: Then shall I be upright, And I shall be clear from great transgression. Let the words of my mouth and the meditation of my heart Be acceptable in thy sight, O Jehovah, my rock, and my redeemer." — Psalms 19:11-14 (ASV)

God's word warns the wicked not to continue in his wicked way, and warns the righteous not to turn from his good way. There is a reward, not only after keeping, but in keeping God's commandments. Religion makes our comforts sweet, and our crosses easy, life truly valuable, and death itself truly desirable.

David not only desired to be pardoned and cleansed from the sins he had discovered and confessed, but also from those he had forgotten or overlooked. All discoveries of sin made to us by the law should drive us to the throne of grace, there to pray. His dependence was the same as that of every Christian who says, Surely in the Lord Jesus have I righteousness and strength.

No prayer can be acceptable before God which is not offered in the strength of our Redeemer or Divine Kinsman, through Him who took our nature upon Himself, so that He might redeem us to God and restore the long-lost inheritance. May our hearts be deeply affected by the excellence of the Word of God; and deeply affected by the evil of sin, the danger we are in from it, and the danger we are in through it.
