He loveth righteousness and judgment. This is a confirmation of the preceding verse, and intimates to us that God of his own nature loves righteousness and equity. It therefore follows, that froward affections cannot hurry him, after the manner of men, to evil devices. At first sight, indeed, this appears but a common commendation of God, and of small importance, because all confess that he observes the most perfect rule of righteousness in all his works. Why then, may some one say, has a new song just been spoken of, as if it had been about some unusual matter? We answer, in the first place, because it is too obvious how wickedly a great part of the world shut their eyes to God's righteousness, while they either carelessly overlook innumerable proofs of his providence, or imagine that they happen by chance. But there is often a worse fault than this; namely, that if our wishes are not gratified, we instantly murmur against God's righteousness; and although the maxim, "God doeth all things righteously," is in every man's mouth, yet scarcely one in a hundred firmly believes it in his heart, otherwise, as soon as this truth is pronounced, "Thus it pleaseth God," every man would obediently submit himself to God's will. Now, as men in adversity are with the utmost difficulty brought to this point - to acknowledge that God is just, and as, in prosperity, they soon fall from the acknowledgement of it, it is not to be wondered at that the prophet, in order to persuade men that God is an upright governor, affirms that he loveth righteousness. Whoever, therefore, has thoroughly embraced this doctrine, let him know that he has profited much. Others explain this to mean, that God loveth righteousness in men. This, indeed, is true; but it is far from the sense of the text, because the design of the Holy Spirit here is to maintain the glory of God in opposition to the poison of ungodliness, which is deeply seated in many hearts. In the second clause of the verse, the Psalmist commends another part of God's excellence, namely, that the earth is full of his goodness The righteousness of God ought justly to incite us to praise him, but his goodness is a more powerful motive; because, the more experience which any man has of his beneficence and mercy, the more strongly is he influenced to worship him. Farther, the discourse is still concerning all the benefits of God which he scatters over the whole human race. These, the inspired writer declares, meet us wherever we turn our eyes.

He loveth righteousness - See Psalm 11:7.
And judgment - justice.
The earth is full of the goodness of the Lord - Margin, "mercy." So the Hebrew. That is, his mercy or goodness is manifest everywhere. Every part of the earth bears witness that he is good.

He loveth righteousness - What he delights in himself, he loves to see in his followers.
The earth is full of the goodness of the Lord - To hear its worthless inhabitants complain, one would think that God dispensed evil, not good. To examine the operation of his hand, every thing is marked with mercy and there is no place where his goodness does not appear. The overflowing kindness of God fills the earth. Even the iniquities of men are rarely a bar to his goodness: he causes his sun to rise on the evil and the good, and sends his rain upon the just and the unjust.

He (e) loveth righteousness and judgment: the earth is full of the goodness of the LORD.
(e) However the world judges God's works, yet he does all things according to justice and mercy.

He loveth righteousness and judgment,.... Or "righteous judgment" (y); he delights in the administration of it himself, Jeremiah 9:24; and he is well pleased with acts of righteousness done by others, when done according to his word, from love to him, by faith in him, and with a view to his glory; especially he loves the righteousness of his son, being satisfactory to his law and justice, and his people, as clothed with it; and he delights in the condemnation of sin in the flesh of Christ, and in the righteous judgment of the world, and the prince of it, by Christ;
the earth is full of the goodness of the Lord; of the providential goodness of God, of which all creatures partake; and of the special goodness or grace of God manifested in Christ Jesus; it was full of it particularly when Christ was here on earth, who is full of grace and truth; and when the Gospel of the grace of God was preached everywhere by his apostles, according to his order, and appeared to all men; and so it will be especially in the latter day, when multitudes will be called by grace and converted, and when the earth will be full of the knowledge of the Lord; and still more when it will become a new earth, wherein only righteous men will dwell.
(y) "judicium justum", Gejerus.

Goodness - He not only doth no man wrong, but he is kind and merciful to all men.
