The prayer in vv. 3, 4, is for deliverance not from dangers, but from temptation to sin in word or deed. The psalmist is not suffering from the hostility of the workers of iniquity, but dreads becoming infected with their sin. This phase of trial was not David's in Absalom's revolt, and the prominence given to it here makes Delitzsch's view of the psalm very doubtful. An earlier psalmist had vowed to "put a muzzle on his mouth," but a man's own guard over his words will fail, unless God keeps the keeper, and, as it were, sets a sentry to watch the lips. The prayer for strength to resist temptation to wrong acts, which follows that against wrong speech, is curiously loaded with synonymous terms. The psalmist asks that his heart, which is but too apt to feel the risings of inclination to fall in with the manners around him, may be stiffened into wholesome loathing of every evil--"To practise practices in wickedness with men [perhaps, _great men_] who work iniquity." The clause rather drags, and the proposed insertion of "Let me not sit" before "with men that work iniquity" lightens the weight, and supplies a good parallel with "Let me not eat of their dainties." It is, however, purely conjectural, and the existing reading is intelligible, though heavy. The psalmist wishes to keep clear of association with the corrupt society around him, and desires to be preserved from temptations to fall in with its luxurious sensuality, lest thereby he should slide into imitation of its sins. He chose plain living, because he longed for high thinking, and noble doing, and grave, reverend speech. All this points to a period when the world fought against goodness by proffering vulgar delights, rather than by persecution. Martyrs have little need to pray that they may not be tempted by persecutors' feasts. This man "scorned delights" and chose to dwell with good men. The connection of ver. 5 with the preceding seems to be that in it the psalmist professes his preference for the companionship of the righteous, even if they reprove him. It is better, in his judgment, to have the wholesome correction of the righteous than to feast with the wicked. But while this is the bearing of the first part of the verse, the last clause is obscure, almost to unintelligibility, and even the earlier ones are doubtful. If the Hebrew accents are adhered to, the rendering above must be adopted. The division of clauses and rendering adopted by Hupfeld and many others, and in the A.V. and R.V., gives vividness, but requires "it shall be" to be twice supplied. The whole sentence seems to run more smoothly, if the above translation is accepted. "Oil for the head" is that with which the head is anointed as for a feast; and there is probably a tacit suggestion of a better festival, spread in the austere abodes of the righteous poor, than on the tables loaded with the dainties of the wicked rich.
