Such high and sweet communion cannot but breed profound distaste for the society of evil-doers. The eyes which have God's loving-kindness ever before them are endowed with penetrative clearness of vision into the true hollowness of most of the objects pursued by men, and with a terrible sagacity which detects hypocrisy and shams. Association with such men is necessary, else we must needs go out of the world, and leaven must be in contact with dough in order to do its transforming work; but it is impossible for a man whose heart is truly in touch with God not to feel ill at ease when brought into contact with those who have no share in his deepest convictions and emotions. "Men of vanity" is a general designation for the ungodly, pronouncing on every such life the sentence that it is devoted to empty unrealities and partakes of the nature of that to which it is given up. One who has Jehovah's loving-kindness before his eyes cannot "sit" with such men in friendly association, as if sharing their ways of thinking, nor "go" with them in their course of conduct. "Those who mask themselves" are another class, namely hypocrites who conceal their pursuit of vanity under the show of religion. The psalmist's revulsion is intensified in ver. 5 into "hate," because the evil-doers and sinners spoken of there are of a deeper tint of blackness, and are banded together in a "congregation," the opposite and parody of the assemblies of the righteous, whom he feels to be his kindred. No doubt separateness from evil-doers is but part of a godly man's duty, and has often been exaggerated into selfish withdrawal from a world which needs good men's presence all the more the worse it is; but it _is_ a part of his duty, and "Come out from among them and be separate" is not yet an abrogated command. No man will ever mingle with "men of vanity," so as to draw them from the shadows of earth to the substance in God, unless his loving association with them rests on profound revulsion from their principles of action. None comes so near to sinful men as the sinless Christ; and if He had not been ever "separate from sinners," He would never have been near enough to redeem them. We may safely imitate His free companionship, which earned Him His glorious name of their Friend, if we imitate His remoteness from their evil.
From the uncongenial companionship of the wicked the psalmist's yearnings instinctively turn to his heart's home, the sanctuary. The more a man feels out of sympathy with a godless world, the more longingly he presses into the depths of communion with God; and, conversely, the more he feels at home in still communion, the more does the tumult of sense-bound crowds grate on his soul. The psalmist, then, in the next group of verses (6, 7), opposes access to the house of God and the solemn joy of thankful praises sounding there to the loathed consorting with evil. He will not sit with men of vanity because he will enter the sanctuary. Outward participation in its worship may be included in his vows and wishes, but the tone of the verses rather points to a symbolical use of the externalities of ritual. Cleansing the hands alludes to priestly lustration; compassing the altar is not known to have been a Jewish practice, and probably is to be taken as simply a picturesque way of describing himself as one of the joyous circle of worshippers; the sacrifice is praise. The psalmist rises to the height of the true Israelite's priestly vocation, and ritual has become transparent to him. None the less may he have clung to the outwardnesses of ceremonial worship, because he apprehended them in their highest significance and had learned that the qualification of the worshipper was purity, and the best offering praise. Well for those who, like him, are driven to the sanctuary by the revulsion from vanities and from those who pursue them!
