Psalms 119:142

It is no wonder that they have forgotten the words of God, who have chosen to set up their own righteousness, ignorant of the righteousness of God; but he, the younger, hath not forgotten, for he hath not wished to have a righteousness of his own, but that of God, of which he now also saith, "Thy righteousness is an everlasting righteousness, and Thy law is the truth" (ver. 142). For how is not the law truth, through which came the knowledge of sin, and that which giveth testimony of the righteousness of God? For thus the Apostle saith: "The righteousness of God is manifested, being witnessed by the Law and the Prophets."

The principles of God's government are permanent and reliable, and in the deepest distress His people find them a theme of delightful meditation and a source of reviving power (Ps 119:17, 116). law is the truth--It therefore cannot deceive as to its promises. everlasting-- (Ps 111:3), though to outward appearance seeming dead.

"Thy righteousness is an everlasting righteousness." Having in a previous verse ascribed righteousness to God, he now goes on to declare that that righteousness is unchanging and endures from age to age. This is the joy and glory of the saints, that what God is he always will be, and his mode of procedure towards the sons of men is immutable: having kept his promise, and dealt out justice among his people, he will do so world without end. Both the righteousnesses and the unrighteousnesses of men come to an end, but the righteousness of God is without end. "And thy law is the truth." As God is love, so his law is the truth, the very essence of truth, truth applied to ethics, truth in action, truth upon the judgment seat. We hear great disputes about, "What is truth?" The holy Scriptures are the only answer to that question. Note, that they are not only true, but the truth itself. We may not say of them that they contain the truth, but that they are the truth: "thy law is the truth." There is nothing false about the law or preceptory part of Scripture. Those who are obedient thereto shall find that they are walking in a way consistent with fact, while those who act contrary thereto are walking in a vain show.

Thy righteousness is an everlasting righteousness - The word צדק tsedek is a word of very extensive meaning in the Bible. It signifies, not only God’s inherent righteousness and perfection of nature, but also his method of treating others; his plan of redemption; his method of saving others. And the word δικαιοσυνη, which answers to it, in the Septuagint and in the New Testament, is used with the same latitude of meaning, and in the same sense; particularly in that remarkable passage, Rom 3:25-26 (note), where see the notes. Thy merciful method of dealing with sinners and justifying the ungodly will last as long as the earth lasts; and thy law that witnesses this, in all its pages, is the truth.
