The "then" of ver. 9 may be either temporal or logical. It may mean "things being so," or "in consequence of this," or it may mean "at the time when," and may refer to the further specification of period in the next clause. That same day which has already been designated as that of the enemies' panting after the psalmist's life, and wresting of his words, and, on the other hand, as that of his fear, is now the time of his prayer, and consequently of their defeat and flight. The confidence which struggled with fear in the closing words of the first part, is now consolidated into certain knowledge that God is on the singer's side, and in a very deep sense belongs to him. This is the foundation of his hope of deliverance; and in this clear knowledge he chants once more his refrain. As is often the case, slight differences, mainly due to artistic love of variety in uniformity, occur in the repeated refrain. "Word" stands instead of "His word"; "man," instead of "flesh"; and a line is intercalated, in which Jehovah is substituted for God. The addition may be a later interpolation, but is probably part of the original text, and due to the same intelligible motives which prompted the occasional use of the great Covenant Name in the Elohistic psalms of this second book. The psalmist's exuberant confidence overflows the limits of his song, in a closing couple of verses which are outside its scheme. So sure is he of deliverance, that, as often in similar psalms, his thoughts are busied in preparing his sacrifice of thanks before the actual advent of the mercy for which it is to be offered. Such swift-footed Gratitude is the daughter of very vivid Faith. The ground of the thankoffering is deliverance of "the soul," for which foes have "waited." "Thou hast delivered" is a perfect tense expressing confidence in the certainty of the as yet unrealised exercise of God's power. The question of ver. 13 _b_, like that of ver. 8 _c_ (and perhaps that of ver. 7 _a_), is an emphatic affirmation, and the verb to be supplied is not "Wilt thou?" as the A.V. has it, but, as is plain from the context, and from the quotation of this verse in Psalm cxvi. 8, "Hast thou?" The Divine deliverance is complete,--not only doing the greater, but also the less; and not barely saving life, but sustaining the steps. God does not rescue by halves, either in the natural or spiritual realm; but in the former He first rescues and next preserves, and in the latter He delivers from the true death of the spirit, and then inspires to glad obedience. The psalm crowns its celebration of God's miracles of deliverance by declaring the aim of them all to be that their recipient may walk before God--_i.e._, in continual consciousness of His cognisance of his deeds, and "in the light of the living" or "of life." The expression seems here to mean simply the present life, as contrasted with the darkness and inactivity of Sheol; but we can scarcely help remembering the deeper
