The final strophe (vv. 7, 8) gives the culmination of faith in prayer. "Arise, Jehovah," is quoted from the ancient invocation (Num. x. 35), and expresses in strongly anthropomorphic form the desire for some interposition of Divine power. Fearlessness is not so complete that the psalmist is beyond the need of praying. He is courageous because he knows that God will help, but he knows, too, that God's help depends on his prayer. The courage which does not pray is foolish, and will break down into panic; that which fears enough to cry "Arise, Jehovah," will be vindicated by victory. This prayer is built on experience, as the preceding confidence was. The enemies are now, according to a very frequent figure in the Psalter, compared to wild beasts. Smiting on the cheek is usually a symbol of insult, but here is better taken in close connection with the following "breaking the teeth." By a daring image Jehovah is represented as dealing the beasts of prey, who prowl round the psalmist with open mouth, the buffets which shatter their jaws and dislodge their teeth, thus making them powerless to harm him. So it has been in the past, and that past is a plea that so it will be now. God will be but doing as He has done, if now He "arise." If He is to be true to Himself, and not to stultify His past deliverances, He must save his suppliant now. Such is the logic of faith, which is only valid on the supposition that God's resources and purpose are inexhaustible and unchangeable. The whole ends with confident anticipation of an answer. "Salvation belongeth unto Jehovah." The full spiritual meaning of that salvation was not yet developed. Literally, the word means "breadth," and so, by a metaphor common to many languages, deliverance as an act, and well-being or prosperity as a state. Deliverance from his enemies is the psalmist's main idea in the word here. It "belongs to Jehovah," since its bestowal is His act. Thus the psalmist's last utterance of trust traverses the scoff which wounded him so much (ver. 2), but in a form which beautifully combines affiance and humility, since it triumphantly asserts that salvation is in God's power, and silently implies that what is thus God's "to will and do" shall certainly be His suppliant's to enjoy.
Intensely personal as the psalm is, it is the prayer of a king; and rebels as the bulk of the people are ("ten thousands of the people"), they are still God's. Therefore all are included in the scope of his pitying prayer. In other psalms evil is invoked on evil-doers, but here hate is met by love, and the self-absorption of sorrow counteracted by wide sympathy. It is a lower exemplification of the same spirit which breathed from the lips of the greater King the prayer, "Father, forgive them, for they know not what they do."
