The character and fate of the lover of the law are sketched in vv. 1-3, and that of the "wicked" in vv. 4-6.
"How abundantly is that word Blessed multiplied in the Book of Psalms! The book seems to be made out of that word, and the foundation raised upon that word, for it is the first word of the book. But in all the book there is not one Woe" (Donne).
It is usually taken as an exclamation, but may equally well be a simple affirmation, and declares a universal truth even more strongly, if so regarded. The characteristics which thus bring blessedness are first described negatively, and that order is significant. As long as there is so much evil in the world, and society is what it is, godliness must be largely negative, and its possessors "a people whose laws are different from all people that be on earth." Live fish swim against the stream; dead ones go with it.
The tender graces of the devout soul will not flourish unless there be a wall of close-knit and unparticipating opposition round them, to keep off nipping blasts. The negative clauses present a climax, notwithstanding the unquestionable correctness of one of the grounds on which that has been denied—namely, the practical equivalence of "wicked" and "sinner."
Increasing closeness and permanence of association are obvious in the progress from walking to standing and from standing to sitting. Increasing boldness in evil is marked by the progress from counsel to way, or course of life, and thence to scoffing. Evil purposes come out in deeds, and deeds are formularised at last in bitter speech. Some men scoff because they have already sinned. The tongue is blackened and made sore by poison in the system. Therefore goodness will avoid the smallest conformity with evil, as knowing that if the hem of the dress or the tips of the hair be caught in the cruel wheels, the whole body will be drawn in. But these negative characteristics are valuable mainly for their efficacy in contributing to the positive, as the wall round a young plantation is there for the sake of what grows behind it. On the other hand, these positive characteristics, and eminently that chief one of a higher love, are the only basis for useful abstinence. Mere conventional, negative virtue is of little power or worth unless it flow from a strong set of the soul in another direction.
"So did not I" is good and noble when we can go on to say, as Nehemiah did, "because of the fear of God." The true way of floating rubbish out is to pour water in. Delight in the law will deliver from delight in the counsel of the wicked. As the negative, so the positive begins with the inward man. The main thing about all men is the direction of their "delight." Where do tastes run? what pleases them most? and where are they most at ease? Deeds will follow the current of desires, and be right if the hidden man of the heart be right. To the psalmist, that law was revealed by Pentateuch and prophets; but the delight in it, in which he recognises the germ of godliness, is the coincidence of will and inclination with the declared will of God, however declared. In effect, he reduces perfection to the same elements as the other psalmist who sang, "I delight to do Thy will, yea, Thy law is within my heart." The secret of blessedness is self-renunciation,—
"A love to lose my will in His,
And by that loss be free."
Thoughts which are sweet will be familiar.
The command to Joshua is the instinct of the devout man. In the distractions and activities of the busy day the law beloved will be with him, illuminating his path and shaping his acts. In hours of rest it will solace weariness and renew strength. That habit of patient, protracted brooding on the revelation of God's will needs to be cultivated. Men live meanly because they live so fast. Religion lacks depth and volume because it is not fed by hidden springs.
The good man's character being thus all condensed into one trait, the psalm next gathers his blessedness up in one image. The tree is an eloquent figure to Orientals, who knew water as the one requisite to turn desert into garden. Such a life as has been sketched will be rooted and steadfast. "Planted" is expressed by a word which suggests fixity. The good man's life is deeply anchored, and so rides out storms. It goes down through superficial fleeting things to that Eternal Will, and so stands unmoved and upright when winds howl. Scotch firs lift massive, corrugated boles, and thrust out wide, gnarled branches clothed in steadfast green, and look as if they could face any tempest, but their roots run laterally among the surface gravel, and therefore they go down before blasts which feeble saplings, that strike theirs vertically, meet unharmed.
