Psalms 119:105

“NUN. Thy word [is] a lamp unto my feet, etc.] The same Solomon says of the law and commandment, the preceptive part of the word, (<200623>Proverbs 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…”

“Thy word is a lamp unto my feet - This begins a new portion of the psalm, indicated by the Hebrew letter Nun (נ n), equivalent to our “n.” The margin here is “candle.” The Hebrew word means a light, lamp, candle. The idea is, that the word of God is like a torch or lamp ton man in a dark night. It shows him the way; it prevents his stumbling over obstacles, or failing down precipices, or wandering off into paths which would lead into danger, or would turn him away altogether from the path to life. Compare the notes at 2 Peter 1:19. And a light unto my path - The same idea substantially is presented here. It is a light which shines on the road that a man treads, so that he may see the path,…”

“word: Psa 19:8, Psa 43:3; Pro 6:23; Eph 5:13; Pe2 1:19 lamp: or, candle, Psa 18:28; Job 29:3 Psalms 119:106”

“The eightfold Nun. The word of God is his constant guide, to which he has entrusted himself for ever. The way here below is a way through darkness, and leads close past abysses: in this danger of falling and of going astray the word of God is a lamp to his feet, i.e., to his course, and a light to his path ( Pro 6:23); his lamp or torch and his sun. That which he has sworn, viz., to keep God's righteous requirements, he has also set up, i.e., brought to fulfilment, but not without being bowed down under heavy afflictions in confessing God; wherefore he prays (as in Psa 119:25) that God would revive him in accordance with His word, which promises life to those who keep it. The confessions of…”
