Here is, 1. David's care to avoid the ways of sin: "I have refrained my feet from the evil ways they were ready to step aside into. I checked myself and drew back as soon as I was aware that I was entering into temptation." Though it was a broad way, a green way, a pleasant way, and a way that many walked in, yet, being a sinful way, it was an evil way, and he refrained his feet from it, foreseeing the end of that way. And his care was universal; he shunned every evil way. By the words of thy lips I have kept myself from the paths of the destroyer, Psa 17:4. 2. His care to be found in the way of duty; That I might keep thy word, and never transgress it. His abstaining from sin was, (1.) An evidence that he did conscientiously aim to keep God's word and had made that his rule. (2.) It was a means of his keeping God's word in the exercises of religion; for we cannot with any comfort or boldness attend on God in holy duties, so as in them to keep his word, while we are under guilt or in any by-way.

NUN.--The Fourteenth Part.

NUN. Thy word is a lamp unto my feet,.... The same Solomon says of the law and commandment, the preceptive part of the word, Pro 6:23; and the Septuagint and Arabic versions render it "law" here. This shows a man what is his duty, both towards God and man; by it is the knowledge of sin: this informs what righteousness that is God requires of men; by the light of it a man sees his own deformity and infirmities, the imperfection of his obedience, and that he needs a better righteousness than his own to justify him in the sight of God; it is a rule of walk and conversation; it directs what to do, and how to walk. The Gospel part of the word is a great and glorious light; by which men come to have some knowledge of God in Christ, as a God gracious and merciful; of Christ, his person, offices, and grace; of righteousness, salvation, and eternal life by him; and it teaches men to live soberly, righteously, and godly. The whole Scripture is a light shining in a dark place; a lamp or torch to be carried in the hand of a believer, while he passes through this dark world; and is in the present state of imperfection, in which he sees things but darkly. This is the standard of faith and practice; by the light of this lamp the difference between true and false doctrine may be discerned; error and immorality may be reproved, and made manifest; the way of truth and godliness, in which a man should walk, is pointed out; and by means of it he may see and shun the stumbling blocks in his way, and escape falling into pits and ditches; it is a good light to walk and work by. The Targum is,

"thy word is as a light that shines to my feet.''

It follows,

and a light unto my path; the same thing in other words. Now it should be observed, that the word of God is only so to a man whose eyes are opened and enlightened by the Spirit of God, which is usually done by means of the word; for a lamp, torch, candle, or any other light are of no use to a blind man.
