In the second part the solitary soul translates its experience into exhortations for all, and woos men to follow on the same path, by setting forth in rich variety the joys of pardon. The exhortation first dwells on the positive blessings associated with penitence (vv. 6, 7), and next on the degradation and sorrow involved in obstinate hard-heartedness (vv. 8-10). The natural impulse of him who has known both is to beseech others to share his happy experience, and the psalmist's course of thought obeys that impulse, for the future "shall pray" (R.V.) is better regarded as hortatory "let ... pray." "Because of this" does not express the contents of the petitions, but their reason. The manifestation of God as infinitely ready to forgive should hearten to prayer; and, since God's beloved need forgiveness day by day, even though they may not have fallen into such gross sin as this psalmist, there is no incongruity in the exhortation being addressed to them. "He that is washed" still needs that feet fouled in muddy ways should be cleansed. Every time of seeking by such prayer is a "time of finding"; but the phrase implies that there is a time of not finding, and, in its very graciousness, is heavy with warning against delay. With forgiveness comes security. The penitent, praying, pardoned man is set as on a rock islet in the midst of floods, whether these be conceived of as temptation to sin or as calamities. The hortatory tone is broken in ver. 7 by the recurrence of the personal element, since the singer's heart was too full for silence; but there is no real interruption, for the joyous utterance of one's own faith is often the most winning persuasive, and a devout man can scarcely hold out to others the sweetness of finding God without at the same time tasting what he offers. Unless he does, his words will ring unreal. "Thou art a shelter for me" (same word as in xxvii. 5, xxxi. 20), is the utterance of trust; and the emphasis is on "my." To hide in God is to be "preserved from trouble," not in the sense of being exempt, but in that of not being overwhelmed, as the beautiful last clause of v. 7 shows, in which "shouts of deliverance" from trouble which had pressed are represented by a bold, but not harsh, metaphor as ringing the psalmist round. The air is filled with jubilant voices, the echoes of his own. The word rendered "songs" or preferably "shouts" is unusual, and its consonants repeat the last three of the preceding word ("shalt preserve me"). These peculiarities have led to the suggestion that we have in it a "dittograph." If so, the remaining words of the last clause would read, "Thou wilt compass me about with deliverance," which would be a perfectly appropriate expression. But probably the similarity of letters is a play upon words, of which we have another example in the preceding clause where the consonants of the word for "trouble," reappear in their order in the verb "wilt preserve." The shout of joy is caught up by the Selah.
