I have chosen the way of truth. In this and the following verse he affirms that he was so disposed as to desire nothing more than to follow righteousness and truth. It is, therefore, with great propriety he employs the term to choose. The old adage, that man's life is as it were at the point where two ways meet, refers not simply to the general tenor of human life, but to every particular action of it. For no sooner do we undertake any thing, no matter how small, than we are grievously perplexed, and as if hurried off by a tempest, are confounded by conflicting counsels. Hence the prophet declares, that in order constantly to pursue the right path, he had resolved and fully determined not to relinquish the truth. And thus he intimates that he was not entirely exempted from temptations, yet that he had surmounted them by giving himself up to the conscientious observance of the law. The last clause of the verse, I have set thy judgments before me, relates to the same subject. There would be no fixed choice on the part of the faithful, unless they steadily contemplate the law, and did not suffer their eyes to wander to and fro. In the subsequent verse he not only asserts his entertaining this holy affection for the law, but also combines it with prayer, that he might not become ashamed and enfeebled under the derision of the ungodly, while he gave himself wholly to the law of God. Here he employs the same term as formerly, when he said his soul cleaved to the dust, and, in doing so, affirms he had so firmly taken hold of God's law, that he cannot be separated from it. From his expressing a fear lest he might be put to shame or overwhelmed with reproach, we learn that the more sincerely a man surrenders himself to God, the more will he be assailed by the tongues of the vile and the venomous.

I have chosen the way of truth - Among all the paths of life I have selected this. I prefer this. I desire to walk in this. Religion is, wherever it exists, a matter of preference or choice; and the friend of God prefers his service to the service of the world.
Thy judgments - Thy statutes; thy laws.
Have I laid before me - I have set them before my mind as the guide of my conduct; I have made their observance the end and aim of my life.

I have chosen the way of truth - And that I may continue in its "remove from me the way of lying." See above.

I have chosen the way of truth,.... Christ, who is the way and the truth, the true way to God and to eternal happiness; and to choose him is to choose the good part, which shall never be taken away; and which choice is made, not by the free will of man, as left to itself, but under the influence and by the direction of the Spirit and grace of God; whereby a soul sees a preferableness in Christ to every thing else, and which determines the choice of him: or, "the way of faith", as the Targum; the doctrine of faith, particularly the doctrine of justification by faith in the righteousness of Christ; also each of the truths of the Gospel, a way in which believers walk with pleasure and by choice; as being preferable to, and more desirable by them, than thousands of gold and silver;
thy judgments have I laid before me; to be looked at continually, as being exceeding amiable and lovely, and having a strong affection for them; and as a copy to write after, and a rule to walk by.

Laid - Or, set before me as a mark to aim at; as a rule to direct me.
