Psalm 111:7

The works of his hands are verity and judgment
His works of providence are just and true, particularly these which respected the driving the Canaanites out of their land, and settling the Israelites in it; these were done according to the truth of the divine promises and prophecies, and so were "verity" or "truth"; and for the sins of the Heathen, and by him who has a right to dispose of the earth and the fulness of it to whom he pleases, and so are "judgment" or righteous; and this holds good of his work of grace upon the heart, which is the work of his hands, and is "truth in the inward parts": and is created in righteousness and true holiness; and of all his acts of grace in election, redemption which are according to the truth of the divine nature and its perfections, and in which there is no unrighteousness. Some interpret this of the two tables of stone, which were the work, writing, and engraving of God, and on which were inscribed the judgments of the Lord; and are "true and righteous altogether". Aben Ezra understands it of the law implanted in the hearts of men.

All his commandments are sure:
firm, and to be believed and complied with, either to destroy the nations, or to possess their land; or rather the commands of the moral law, which are firm and sure, one jot or tittle of which shall never pass away; all have been fulfilled by Christ, and remain with him a rule of walk and conversation; or the word which the Lord has commanded to a thousand generations, ( Psalms 105:8 ) the covenant which is ordered in all things and sure; the promises of which are yea and amen in Christ; and the blessings of it, the sure mercies of David; and even the doctrines of the Gospel are the commandments and testimony of the Lord, which are sure, ( Psalms 19:8 ) and to be believed, being the word of truth, the Gospel of our salvation, and coming from God, who cannot lie.
