That petition is, like others in similar psalms, proper to the spiritual level of the Old Testament, and not to that of the New; and it is far more reverent, as well as accurate, to recognise fully the distinction than to try to slur it over. At the same time, it is not to be forgotten that the same lofty consciousness of the identity of his cause with God's, which we have already had to notice, operating here in these wishes for the enemies' destruction, gives another aspect to them than that of mere outbursts of private vengeance. That higher aspect is made prominent by the addition "in Thy troth." God's faithfulness to His purposes and promises was concerned in the destruction, because these were pledged to the psalmist's protection. His well-being was so intertwined with God's promises that the Divine faithfulness demanded the sweeping away of his foes. That is evidently not the language which fits our lips. It implies a special relation to God's plans, and it modifies the character of this apparently vindictive prayer.
The closing verses of this simple, little psalm touch very familiar notes. The faith which has prayed has grown so sure of answer that it already begins to think of the thank-offerings. This is not like the superstitious vow, "I will give so-and-so if Jupiter"--or the Virgin--"will hear me." This praying man knows that he is heard, and is not so much vowing as joyfully anticipating his glad sacrifice. The same incipient personification of the name as in ver. 1 is very prominent in the closing strains. Thank-offerings--not merely statutory and obligatory, but brought by free, uncommanded impulse--are to be offered to "Thy name," because that name is good. Ver. 7 probably should be taken as going even further in the same direction of personification, for "Thy name" is probably to be taken as the subject of "hath delivered." The tenses of the verbs in ver. 7 are perfects. They contemplate the deliverance as already accomplished. Faith sees the future as present. This psalmist, surrounded by strangers seeking his life, can quietly stretch out a hand of faith, and bring near to himself the to-morrow when he will look back on scattered enemies and present, glad sacrifices! That power of drawing a brighter future into a dark present belongs not to those who build anticipations on wishes, but to those who found their forecasts on God's known purpose and character. _The name_ is a firm foundation for hope. There is no other.
The closing words express confidence in the enemies' defeat and destruction, with a tinge of feeling that is not permissible to Christians. But the supplement, "my desire," is perhaps rather too strongly expressive of wish for their ruin. Possibly there needs no supplement at all, and the expression simply paints the calm security of the man protected by God, who can "look upon" impotent hostility without the tremor of an eyelid, because he knows who is his Helper.
