How long will ye imagine mischief against a man? It is always best to begin with God, and then we may confront our enemies. Make all sure with heaven, then may you grapple with earth and hell. David expostulates with his insensate foes; he marvels at their dogged perseverance in malice, after so many failures and with certain defeat before them. He tells them that their design was an imaginary one, which they never could accomplish however deeply they might plot. It is a marvel that men will readily enough continue in vain and sinful courses, and yet to persevere in grace is so great a difficulty as to be an impossibility, were it not for divine assistance. The persistency of those who oppose the people of God is so strange that we may well expostulate with them and say, "How long will ye thus display your malice?" A hint is given in the text as to the cowardliness of so many pressing upon one man; but none are less likely to act a fair and manly part than those who are opposed to God's people for righteousness' sake. Satan could not enter into combat with Job in fair duel, but must needs call in the Sabeans and Chaldeans, and even then must borrow the lightning and the wind before his first attack was complete. If there were any shame in him, or in his children, they would be ashamed of the dastardly manner in which they have waged war against the seed of the woman. Ten thousand to one has not seemed to them too mean an advantage; there is not a drop of chivalrous blood in all their veins. Ye shall be slain all of you. Your edged tools will cut your own fingers. Those who take the sword shall perish with the sword. However many or fierce the bands of the wicked may be, they shall not escape the just retribution of heaven; rigorously shall the great Lawgiver exact blood from men of blood, and award death to those who seek the death of others.
As a bowing wall shall ye be, and as a tottering fence. Boastful persecutors bulge and swell with pride, but they are only as a bulging wall ready to fall in a heap; they lean forward to seize their prey, but it is only as a tottering fence inclines to the earth upon which it will soon lie at length. They expect men to bow to them, and quake for fear in their presence; but men made bold by faith see nothing in them to honour, and very, very much to despise. It is never well on our part to think highly of ungodly persons; whatever their position, they are near their destruction, they totter to their fall; it will be our wisdom to keep our distance, for no one is advantaged by being near a falling wall; if it does not crush with its weight, it may stifle with its dust. The passage is thought to be more correctly rendered as follows: —"How long will ye press on one man, that ye may crush him in a body, like a toppling wall, a sinking fence?" (So Dr. Kay, of Calcutta, translates it.) We have, however, kept to our own version as yielding a good and profitable meaning. Both senses may blend in our meditations; for if David's enemies battered him as though they could throw him down like a bulging wall, he, on the other hand, foresaw that they themselves would by retributive justice be overthrown like an old crumbling, leaning, yielding fence.
