I called to mind thy judgments of old, O Jehovah! In this psalm, the judgments of God are generally taken for his statutes and decrees, that is, his righteousness. [1] In this place, in consequence of the qualifying phrase, of old, it is more probable that they refer to the examples by which God has made himself known as the righteous Judge of the world. Why does he say that the law of God has been from everlasting? This may to some extent be accounted for from the righteousness here mentioned not being of recent growth, but truly everlasting, because the written law is just an attestation of the law of nature, through means of which God recalls to our memory that which he has previously engraved on our hearts. I am rather inclined to adopt another interpretation, That David remembered the judgments of God, by which he testified that he had established his law perpetually in the world, Such a settlement is very necessary for us; because, when God does not make bare his arm, his word frequently produces little impression. But when he takes vengeance upon the ungodly, he confirms what he had spoken; and this is the reason why in civil law penalties are called confirmations. The term accords better with God's judgments, by which he establishes the authority of his law, as if a true demonstration accompanied his words. And seeing he declares that he called to mind the most ancient of God's judgments, it becomes us to learn, that if his judgments are not displayed as frequently as we would desire, for the strengthening of our faith, this is owing to our ingratitude and apathy; for in no past age have there been wanting clear demonstrations for this very purpose; and thus it may with truth be affirmed, that God's judgments have flowed in one continued manner from age to age, and that the reason why we have not perceived them is, our not deigning to open our eyes to behold them. If any one object, that it is contrary to the nature of his judgments to afford consolation to because they are calculated rather to strike us with terror, the answer is at handy -- that the faithful are made to tremble for fear of God's judgments, as far as is requisite for the mortification of their flesh. On the other hand, these supply them with a large source of consolation, from the fact of their learning from them, that God exercises his superintending providence over the human race. Farther, they learn, that after the wicked have reveled in licentiousness for a season, they shall at length be sisted before the judgment-seat of God; but that they themselves, after having patiently combated under such a Guardian of their welfare, can be in no doubt about their preservation.

I remembered - In my troubles.
Thy judgments of old - The word "judgments" here seems to refer to the divine dealings, whether expressed in the law of God, or in the actual administration of his government over the world. The words "of old" do not seem here to refer to the "eternity past," as the phrase sometimes does now, but to the constancy and uniformity of the principles of the divine administration. The psalmist remembered that the principles of that administration had been always the same; that the law of God was always the same; and that, therefore, he might confide in God. What God had done formerly he would do now; the favor which he had shown in times past he would continue to show now. In the trials of life, in the changes which occur, in the apparent wreck of things, in the fearful prospect of disaster and ruin at any time, it is well for us to think of the unchanging principles which mark the divine dealings. Under such an administration, all who put their trust in God must be safe.
And have comforted myself - I have found consolation in this. When all else seemed to fail, it was a comfort to reflect that an unchangeable God presided over the affairs of people. We could not put confidence in a God given to change.

I remembered thy judgments of old - The word judgments is here taken for providential dealing; and indeed kind treatment; that which God showed to the Hebrews in bearing with and blessing them. And it was the recollection of these judgments that caused him to comfort himself.

I remembered thy (c) judgments of old, O LORD; and have comforted myself.
(c) That is, the examples, by which you declare yourself to be judge of the world.

I remembered thy judgments of old, O Lord,.... Either the judgments of God executed on wicked men; as the bringing a flood on the world of the ungodly; the burning of Sodom and Gomorrah; the destruction of Pharaoh and his host in the Red sea; the cutting off of the Canaanites, and dispossessing them of their land: or the providential dispensations of God towards his own people; who sometimes chastises and corrects them, and brings them very low, and then raises them up again, as in the case of Job. These things the psalmist called to remembrance, and revolved them in his mind, which gave him pleasure and comfort:
and have comforted myself; with such thoughts as these, that that God, who had cast down the mighty from their seats, and had scattered the proud in the imaginations of their hearts, and destroyed them, could easily rebuke the proud that had him in derision; and he that had shown himself so good and gracious to his people, when brought low, could raise him out of his afflictions and distresses.

The pious take comfort, when harassed and distressed by wickedness of men who forsake God's law, in remembering that the great principles of God's truth will still abide; and also God's
judgments of old--that is, His past interpositions in behalf of His people are a pledge that He will again interpose to deliver them; and they become the theme of constant and delightful meditation. The more we keep the more we love the law of God.

Judgments - Thy ancient dispensations to the children of men in punishing the ungodly.
