I have {b} sworn, and I will perform it, that I will keep thy righteous judgments.

(b) So all the faithful ought to bind themselves to God by a solemn oath and promises to stir up their zeal to embrace God's word.

Jamieson-Fausset-Brown Bible Commentary

106-108. Such was the national covenant at Sinai and in the fields of Moab.

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Verse 106

Here is, 1. The notion David had of religion; it is keeping God's righteous judgments. God's commands are his judgments, the dictates of infinite wisdom. They are righteous judgments, consonant to the eternal rules of equity, and it is our duty to keep them carefully. 2. The obligation he here laid upon himself to be religious, binding himself, by his own promise, to that which he was already bound to by the divine precept, and all little enough. "I have sworn (I have lifted up my head to the Lord, and I cannot go back) and therefore must go forward: I will perform it." Note, (1.) It is good for us to bind ourselves with a solemn oath to be religious. We must swear to the Lord as subjects swear allegiance to their sovereign, promising fealty, appealing to God concerning our sincerity in this promise, and owning ourselves liable to the curse of we do not perform it. (2.) We must often call to mind the vows of God that are upon us, and remember that we have sworn. (3.) We must make conscience of performing unto the Lord our oaths (an honest man will be as good as his word); nor have we sworn to our own hurt, but it will be unspeakably to our hurt if we do not perform.
