Verse 111. - Thy testimonies have I taken as an heritage forever. I regard thy Law as my best and most valuable inheritance - one with which I am resolved never to part. For they are the rejoicing of my heart. My chief joy and delight (comp. vers. 16, 24, 35, 47, etc.).

119:105-112 The word of God directs us in our work and way, and a dark place indeed the world would be without it. The commandment is a lamp kept burning with the oil of the Spirit, as a light to direct us in the choice of our way, and the steps we take in that way. The keeping of God's commands here meant, was that of a sinner under a dispensation of mercy, of a believer having part in the covenant of grace. The psalmist is often afflicted; but with longing desires to become more holy, offers up daily prayers for quickening grace. We cannot offer any thing to God, that he will accept but what he is pleased to teach us to do. To have our soul or life continually in our hands, implies constant danger of life; yet he did not forget God's promises nor his precepts. Numberless are the snares laid by the wicked; and happy is that servant of God, whom they have not caused to err from his Master's precepts. Heavenly treasures are a heritage for ever; all the saints accept them as such, therefore they can be content with little of this world. We must look for comfort only in the way of duty, and that duty must be done. A good man, by the grace of God, brings his heart to his work, then it is done well.Thy testimonies have I taken as an heritage for ever,.... The Scriptures, which testify of Christ and of his grace, and of the mind and will of God, are a portion of themselves; and a goodly heritage they are, better than thousands of gold and silver, preferable to all worldly inheritances; as they have been to many, who have forsaken all for Christ and his Gospel. These, like an inheritance, have been transmitted from father to son, from one age of the church to another, in successive generations; nor shall they depart from her, nor from her seed and seed's seed, from henceforth and for ever; they are an inheritance which will continue for ever, Deuteronomy 33:4. These David chose and took, as for his counsellors, so for his portion and inheritance; and a wise and good choice he made; he chose the good part that should never be taken away; his reason for it follows:

for they are the rejoicing of my heart; the doctrines in them, the promises of them, when read or heard explained, gave him a sensible pleasure; revived his heart, and cheered his spirits, supported him under all his troubles, and caused him to go on his way rejoicing; see Jeremiah 15:16.
