But there is more than a negative side to the relation between God and evil, which the psalm goes on to paint in sombre colours, for God not only does not delight in sin, but hates it with a hatred like the physical loathing of some disgusting thing, and will gather all His alienation into one fatal lightning bolt. Such thoughts do not exhaust the truth as to the Divine relation to sin. They did not exhaust the psalmist's knowledge of that relation, and still less do they exhaust ours, but they are parts of the truth to-day as much as then, and nothing in Christ's revelation has antiquated them.
The psalmist's vocabulary is full of synonyms for sin, which witness to the profound consciousness of it which law and ritual had evoked in devout hearts. First, he speaks of it in the abstract, as "wickedness" and "evil." Then he passes to individuals, of whom he singles out two pairs, the first a more comprehensive and the second a more specific designation. The former pair are "the foolish" and "workers of iniquity." The word for "foolish" is usually translated by the moderns "arrogant," but the parallelism with the general expression "workers of iniquity" rather favours a less special meaning, such as Hupfeld's "fools" or the LXX.'s "transgressors." Only in the last pair are special forms of evil mentioned, and the two selected are significant of the psalmist's own experience. _Liars_ and _men of blood and craft_ are his instances of the sort of sinners most abominable to God. That specification surely witnesses to his own sufferings from such.
In ver. 7 the psalmist comes back to the personal reference, contrasting his own access to God with the separation of evil-doers from His presence. But he does not assert that he has the right of entrance because he is pure. Very strikingly he finds the ground of his right of entry to the palace in God's "multitude of mercy," not in his own innocence. Answering to "in Thy righteousness" is "in Thy fear." The one phrase expresses God's disposition to man which makes access possible, the other man's disposition to God which makes worship acceptable. "In the multitude of Thy mercy" and "in Thy fear," taken together, set forth the conditions of approach. Having regard to ver. 4, it seems impossible to restrict the meaning of "Thy house" to the material sanctuary. It is rather a symbol of communion, protection, and friendship. Does the meaning pass into the narrower sense of outward worship in the material "temple" in the second clause? It may be fairly taken as doing so (Hupfeld). But it may be maintained that the whole verse refers to the spiritual realities of prayer and fellowship, and not at all to the externalities of worship, which are used as symbols, just as in ver. 3 prayer is symbolised by the morning sacrifice. But probably it is better to suppose that the psalmist's faith, though not tied to form, was fed by form, and that symbol and reality, the outward and the inward worship, the access to the temple and the approach of the silent soul to God, are fused in his psalm as they tended to be in his experience. Thus the first part of the psalm ends with the psalmist prostrate (for so the word for "worship" means) before the palace sanctuary of his King and God. It has thus far taught the conditions of approach to God, and given a concrete embodiment of them in the progress of the singer's thoughts from petition to assurance and from resolve to accomplishment.
The second part may be taken as his prayer when in the temple, whether that be the outward sanctuary or no. It is likewise a further carrying out of the contrast of the condition of the wicked and of the lovers of God, expressed in terms applying to outward life rather than to worship. It falls into three parts: the personal prayer for guidance in life, the contemplation of evil-doers, and the vehement prayer for their destruction, corresponding to vv. 4-6, and the contrasted prayer for the righteous, among whom he implies his own inclusion.
