There were they in great fear - Margin, as in Hebrew, “they feared a fear.” The idea is, that they were in great terror or consternation. They were not calm in their belief that there was no God. They endeavored to be. They wished to satisfy themselves that there was no God, and that they had nothing to dread. But they could not do this. In spite of all their efforts, there was such proof of his existence, and of his being the friend of the righteous, and consequently the enemy of such as they themselves were, as to fill their minds with alarm. People cannot, by an effort of will, get rid of the evidence that there is a God. In the face of all their attempts to convince themselves of this, the demonstration of his existence will press upon them, and will often fill their minds with terror.
For God is in the generation of the righteous - The word “generation” here, as applied to the righteous, seems to refer to them as a “race,” or as a “class” of people. Compare Psalms 24:6; Psalms 73:15; Psalms 112:2. It commonly in the Scriptures refers to a certain age or duration, as it is used by us, reckoning an age or generation as about thirty or forty years (compare Job 42:16); but in the use of the term before us the idea of an “age” is dropped, and the righteous are spoken of merely as a “class” or “race” of persons. The idea here is, that there were such manifest proofs that God was among the righteous, and that he was their friend, that the wicked could not resist the force of that evidence, however much they might desire it, and however much they might wish to arrive at the conclusion that there was no God. The evidence that he was among the righteous would, of course, alarm them, because the very fact that he was the friend of the righteous demonstrated that he must be the enemy of the wicked, and, of course, that they were exposed to his wrath.
