From the midst of this sad narrative of faithlessness, springs up, like a fountain in a weary land, or a flower among half-cooled lava blocks, the lovely description of God's forbearance in vv. 38, 39. It must not be read as if it merely carried on the narrative, and was in continuation of the preceding clauses. The psalmist does not say "He _was_ full of compassion," though that would be much, in the circumstances; but he is declaring God's eternal character. His compassions are unfailing. It is always His wont to cover sin and to spare. Therefore He exercised these gracious forbearances towards those obstinate transgressors. He was true to His own compassion in remembering their mortality and feebleness. What a melancholy sound, as of wind blowing among forgotten graves, has that summing up of human life as "a breath that goes and comes not again"! With ver. 40 the second portion of the psalm may be regarded as beginning. The first group of historical details dealt first with God's mercies, and passed on to man's requital. The second starts with man's ingratitude, which it paints in the darkest colours, as provoking Him, grieving Him, tempting Him, and vexing Him. The psalmist is not afraid to represent God as affected with such emotions by reason of men's indifference and unbelief. His language is not to be waved aside as anthropomorphic and antiquated. No doubt, we come nearer to the unattainable truth, when we conceive of God as grieved by men's sins and delighting in their trust, than when we think of Him as an impassive Infinitude, serenely indifferent to tortured or sinful hearts. For is not His name of names Love? The psalmist traces Israel's sin to forgetfulness of God's mercy, and thus glides into a swift summing up of the plagues of Egypt, regarded as conducing to Israel's deliverance. They are not arranged chronologically, though the list begins with the first. Then follow three of those in which animals were the destroyers: namely, the fourth, that of flies; the second, that of frogs; and the eighth, that of locusts. Then comes the seventh, that of hail; and, according to some commentators, the fifth, that of the murrain, in ver. 49, followed by the tenth in ver. 51. But the grand, sombre imagery of ver. 49 is too majestic for such application. It rather sums up the whole series of plagues, likening them to an embassy (lit., a sending) of angels of evil. They are a grim company to come forth from His presence--Wrath, Indignation, and Trouble. The same power which sent them out on their errand prepared a way before them; and the crowning judgment, which, in the psalmist's view was also the crowning mercy, was the death of the first-born.
