(11) Thy word.--A different term to that in Psalm 119:9. The two are interchanged throughout the psalm.

Hid . . .--As the Oriental hid treasures. (Comp Matthew 13:44.)

In mine heart, that I might not sin against thee.--The best comment on this is contained in our Lord's words (Matthew 15:19).

Verse 11. - Thy Word have I hid in mine heart, that I might not sin against thee; rather, thy promise (imrah). To have God's word of promise laid up in the heart is the only security against being surprised into sin.

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.Thy word have I hid in mine heart,.... Not only heard and read it, but received it into his affections; mixed it with faith, laid it up in his mind and memory for future use; preserved it in his heart as a choice treasure, where it might dwell richly, and be of service to him on many occasions; and particularly be of the following use:

that I might not sin against thee; the word of God is a most powerful antidote against sin, when it has a place in the heart; not only the precepts of it forbid sin, but the promises of it influence and engage to purity of heart and life, and to the perfecting of holiness in the fear of the Lord; and all the doctrines of grace in it effectually teach the saints to deny all sin and worldly lusts, and to live a holy life and conversation; see 2 Corinthians 7:1.
