Moreover by them is thy servant warned: and in keeping of them there is great {k} reward.

(k) For God accepts our endeavour though it is far from perfect.

Matthew Henry's Concise Commentary

19:11-14 God's word warns the wicked not to go on 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 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 with 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 him, that he might redeem us unto God, and restore the long-lost inheritance. May our hearts be much affected with the excellence of the word of God; and much affected with the evil of sin, and the danger we are in of it, and the danger we are in by it.
