The wicked plotteth against the righteous. David here anticipates an objection which might have been taken to the preceding verse. Where, it might be said, can tranquillity and joy be found when the wicked are mad with rage, and plot every kind of mischief against the children of God? And how shall they cherish good hope for the future who see themselves surrounded with innumerable sources of death? David therefore replies, That although the life of the godly should be assailed by many dangers, yet they are secure in the aid and protection of God; and that however much the wicked should plot against them, they shall be continually preserved. Thus, the design of David is to obviate our fears, lest the malice of the ungodly should terrify us above measure, as if they had the power of doing with us according to their pleasure. He indeed confesses that they are not only full of fraud, and expert in deceiving, but also that they burn with anger, and a raging desire of doing mischief, when he says, that they plot mischief deceitfully against the righteous, and gnash upon them with their teeth But after making this statement, he immediately adds, that their endeavors shall be vain. Yet he seems to provide very coldly for our consolation under sorrow, for he represents God as merely laughing But if God values highly our salvation, why does he not set himself to resist the fury of our enemies, and vigorously oppose them? We know that this, as has been said in Psalm 2:4, is a proper trial of our patience, when God does not come forth at once, armed for the discomfiture of the ungodly, but connives for a time and withholds his hand. But as the eye of sense in such circumstances reckons that he delays his coming too long, and from that delay concludes that he indulges in ease, and feels no interest in the affairs of men, it is no small consolation to be able by the eye of faith to behold him laughing; for then we are assured that he is not seated idly in heaven, nor closes his eyes, resigning to chance the government of the world, but purposely delays and keeps silence because he despises their vanity and folly. And lest the flesh should still murmur and complain, demanding why God should only laugh at the wicked, and not rather take vengeance upon them, the reason is added, that he sees the day of their destruction at hand: For he seeth that his day [1] is coming. Whence is it that the injuries we sustain from the wickedness of man so trouble us, if it be not that, when not obtaining a speedy redress, we begin to despair of ever seeing a better state of things? But he who sees the executioner standing behind the aggressor with drawn sword no longer desires revenge, but rather exults in the prospect of speedy retribution. David, therefore, teaches us that it is not meet that God, who sees the destruction of the wicked to be at hand, should rage and fret after the manner of men. There is then a tacit distinction here made between God and men, who, amidst the troubles and confusions of the world, do not see the day of the wicked coming, and who, oppressed by cares and fears, cannot laugh, but because vengeance is delayed, rather become so impatient that they murmur and fret. It is not, however, enough for us to know that God acts in a manner altogether different from us, unless we learn to weep patiently whilst he laughs, so that our tears may be a sacrifice of obedience. In the meantime, let us pray that he would enlighten us by his light, for by this means alone will we, by beholding with the eye of faith his laughter, become partakers thereof, even in the midst of sorrow. Some, indeed, explain these two verses in another sense; as if David meant to say, that the faithful live so happily that the wicked envy them. But the reader will now perceive that this is far from the design of the prophet.

Footnotes

1 - "Day is often used," says Ainsworth, "for the time of punishment; as, the posterity shall be astonied at his day,' Job 18:20; Woe unto them, for their day is come!' Jeremiah 50:27. So the day of Midian,' Isaiah 9:4; the day of Jezreel,' Hosea 1:11; the day of Jerusalem,' Psalm 137: 7."

The wicked plotteth against the just - Margin, "practiceth." The Hebrew word means to plot; to lie in wait; to plan; to purpose; to devise. See Psalm 31:13. The meaning is, that wicked people lay their plans against the righteous, but that they will not be able to carry them out, or accomplish them, for they will be cut off, and the Lord will protect His friends.
And gnasheth upon him with his teeth - An expression of rage or anger. See the notes at Psalm 35:16.

(i) The wicked plotteth against the just, and gnasheth upon him with his teeth.
(i) The godly are assured that the power and craft of the wicked will not prevail against them, but fall on their own necks and therefore should patiently abide God's time, and in the meanwhile bewail their sins, and offer up their tears as a sacrifice of their obedience.

The wicked plotteth against the just,.... Forms schemes to make him uneasy, uncomfortable, and unhappy:
and gnasheth upon him with his teeth: which expresses his malice and hatred, as David's enemies did upon him, Psalm 35:16; and Stephen's, Acts 7:54.

gnasheth . . . teeth--in beastly rage.

The verb זמם is construed with ל of that which is the object at which the evil devices aim. To gnash the teeth (elsewhere also: with the teeth) is, as in Psalm 35:16, cf. Job 16:9, a gesture of anger, not of mockery, although anger and mockery are usually found together. But the Lord, who regards an assault upon the righteous as an assault upon Himself, laughs (Psalm 2:4) at the enraged schemer; for He, who orders the destinies of men, sees beforehand, with His omniscient insight into the future, his day, i.e., the day of his death (1-Samuel 26:10), of his visitation (Psalm 137:7, Obadiah 1:12, Jeremiah 50:27, Jeremiah 50:31).
