The twofold emotions of ver. 6 recur in vv. 7, 8, where we have first renewed despondency and then reaction into hope. The imagery of floods lifting up their voices, and cataracts sounding as they fall, and breaking waves rolling over the half-drowned psalmist has been supposed to be suggested by the scenery in which he was; but the rushing noise of Jordan in its rocky bed seems scarcely enough to deserve being described as "flood calling to flood," and "breakers and rollers" is an exaggeration if applied to any commotion possible on such a stream. The imagery is so usual that it needs no assumption of having been occasioned by the poet's locality. The psalmist paints his calamities as storming on him in dismal continuity, each "flood" seeming to summon its successor. They rush upon him, multitudinous and close following; they pour down on him as with the thunder of descending cataracts; they overwhelm him like the breakers and rollers of an angry ocean. The bold metaphors are more striking when contrasted with the opposite ones of the first part. The dry and thirsty land there and the rush of waters here mean the same thing, so flexible is nature in a poet's hands.
Then follows a gleam of hope, like a rainbow spanning the waterfall. With the alternation of mood already noticed as characteristic, the singer looks forward, even from the midst of overwhelming seas of trouble, to a future day when God will give His angel, Mercy or Loving-kindness, charge concerning him and draw him out of many waters. That day of extrication will surely be followed by a night of music and of thankful prayer (for supplication is not the only element in prayer) to Him who by His deliverance has shown Himself to be the "God of" the rescued man's "life." The epithet answers to that of the former part, "the living God," from which it differs by but one additional letter. He who has life in Himself is the Giver and Rescuer of our lives, and to Him they are to be rendered in thankful sacrifice. Once more the contending currents meet in vv. 9 and 10, in the former of which confidence and hope utter themselves in the resolve to appeal to God and in the name given to Him as "my Rock"; while another surge of despondency breaks, in the question in which the soul interrogates God, as the better self had interrogated her, and contrasts almost reproachfully God's apparent forgetfulness, manifested by His delay in deliverance, with her remembrance of Him. It is not a question asked for enlightenment's sake, but is an exclamation of impatience, if not of rebuke. Ver. 10 repeats the enemies' taunt, which is there represented as like crushing blows which broke the bones. And then once more above this conflict of emotion soars the clear note of the refrain, summoning to self-command, calmness, and unfaltering hope.
But the victory is not quite won, and therefore Psalm xliii. follows. It is sufficiently distinct in tone to explain its separation from the preceding, inasmuch as it is prayer throughout, and the note of joy is dominant, even while an undertone of sadness links it with the previous parts. The unity is vouched by the considerations already noticed, and by the incompleteness of Psalm xlii. without such triumphant close and of Psalm xliii. without such despondent beginning. The prayer of vv. 1, 2, blends the two elements, which were at war in the second part; and for the moment the darker is the more prominent. The situation is described as in the preceding parts. The enemy is called a "loveless nation." The word rendered "loveless" is compounded of the negative prefix and the word which is usually found with the meaning of "one whom God favours," or visits with loving-kindness. It has been much disputed whether its proper signification is active (one who shows loving-kindness) or passive (one who receives it). But, considering that loving-kindness is in the Psalter mainly a Divine attribute, and that, when a human excellence, it is regarded as derived from and being the echo of experienced Divine mercy, it is best to take the passive meaning as the principal, though sometimes, as unmistakably here, the active is more suitable. These loveless people are not further defined, and may either have been Israelites or aliens. Perhaps there was one "man" of special mischief prominent among them, but it is not safe to treat that expression as anything but a collective. Ver. 2 looks back to xlii. 9, the former clause in each verse being practically equivalent, and the second in xliii. being a quotation of the second in ver. 9, with a variation in the form of the verb to suggest more vividly the picture of weary, slow, dragging gait, fit for a man clad in mourning garb.
