The entrance of thy {b} words giveth light; it giveth understanding unto the simple.

(b) The simple idiots that submit themselves to God have their eyes opened and their minds illuminated, as soon as they begin to read God's word.

Jamieson-Fausset-Brown Bible Commentary

130. The entrance-literally, "opening"; God's words, as an open door, let in light, or knowledge. Rather, as Hengstenberg explains it, "The opening up," or, "explanation of thy word." To the natural man the doors of God's Word are shut. Lu 24:27, 31; Ac 17:3; Eph 1:18, confirm this view, "opening (that is, explaining) and alleging," &c.

unto the simple-those needing or desiring it (compare Ps 19:7).

Matthew Henry's Concise Commentary

119:129-136 The wonders of redeeming love will fix the heart in adoration of them. The Scriptures show us what we were, what we are, and what we shall be. They show us the mercy and the justice of the Lord, the joys of heaven, and the pains of hell. Thus they give to the simple, in a few days, understanding of those matters, which philosophers for ages sought in vain. The believer, wearied with the cares of life and his conflicts with sin, pants for the consolations conveyed to him by means of the sacred word. And every one may pray, Look thou upon me, and be merciful unto me as thou usest to do unto those that love thy name. We must beg that the Holy Spirit would order our steps. The dominion of sin is to be dreaded and prayed against by every one. The oppression of men is often more than flesh and blood can bear; and He who knoweth our frame, will not refuse to remove it in answer to the prayers of his people. Whatever obscurity may appear as to the faith of the Old Testament believers, their confidence at the throne of grace can only be explained by their having obtained more distinct views of gospel privileges, through the sacrifices and services of their law, than is generally imagined. Go to the same place, plead the name and merits of Jesus, and you will not, you cannot plead in vain. Commonly, where there is a gracious heart, there is a weeping eye. Accept, O Lord, the tears our blessed Redeemer shed in the days of his flesh, for us who should weep for our brethren or ourselves.

Matthew Henry's Whole Bible Commentary

Verse 130

Here is, 1. The great use for which the word of God was intended, to give light, that is, to give understanding, to give us to understand that which will be of use to us in our travels through this world; and it is the outward and ordinary means by which the Spirit of God enlightens the understanding of all that are sanctified. God's testimonies are not only wonderful for the greatness of them, but useful, as a light in a dark place. 2. Its efficacy for this purpose. It admirably answers the end; for, (1.) Even the entrance of God's word gives light. If we begin at the beginning, and take it before us, we shall find that the very first verses of the Bible give us surprising and yet satisfying discoveries of the origin of the universe, about which, without that, the world is utterly in the dark. As soon as the word of God enters into us, and has a place in us, it enlightens us; we find we begin to see when we begin to study the word of God. The very first principles of the oracles of God, the plainest truths, the milk appointed for the babes, bring a great light into the soul, much more will the soul be illuminated by the sublime mysteries that are found there. "The exposition or explication of thy word gives light;" then it is most profitable when ministers do their part in giving the sense, Neh. 8:8. Some understand it of the New Testament, which is the opening or unfolding of the Old, which would give light concerning life and immortality. (2.) It would give understanding even to the simple, to the weakest capacities; for it shows us a way to heaven so plain that the wayfaring men, though fools, shall not err therein.
