Verse 16. - I will delight myself in thy statutes (comp. vers. 24, 40, 47, 70, 77, etc.; and see also Psalm 1:2). I will not forget thy Word. That which is "laid up in the heart" (ver. 11) can never be forgotten.

119:9-16 To original corruption all have added actual sin. The ruin of the young is either living by no rule at all, or choosing false rules: let them walk by Scripture rules. To doubt of our own wisdom and strength, and to depend upon God, proves the purpose of holiness is sincere. God's word is treasure worth laying up, and there is no laying it up safe but in our hearts, that we may oppose God's precepts to the dominion of sin, his promises to its allurements, and his threatenings to its violence. Let this be our plea with Him to teach us his statutes, that, being partakers of his holiness, we may also partake of his blessedness. And those whose hearts are fed with the bread of life, should with their lips feed many. In the way of God's commandments there is the unsearchable riches of Christ. But we do not meditate on God's precepts to good purpose, unless our good thoughts produce good works. I will not only think of thy statutes, but do them with delight. And it will be well to try the sincerity of our obedience by tracing the spring of it; the reality of our love by cheerfulness in appointed duties.I will delight myself in thy statutes,.... In looking over them; in meditating on them; in obeying them, and walking according to them; as every good man does delight in the law of the Lord, after the inward man, Romans 7:22; see Psalm 119:24;

I will not forget thy word: he took all proper methods to fix it in his memory; he laid it up in his mind; he meditated upon it in his heart, and he talked of it with his lips, Psalm 119:11.
