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.
