We may observe here,

I.The judgments of God which should certainly come upon these malicious persecutors of David. Though they encouraged themselves in their wickedness, here is that which, if they would believe and consider it, was enough to discourage them. And it is observable how the punishment answers the sin. 1. They shot at David secretly and suddenly, to wound him; but God shall shoot at them, for the ordains his arrows against the persecutors (Psa 7:13), against the face of them, Psa 21:12. And God's arrows will hit surer, and fly swifter, and pierce deeper, than theirs do or can. They have many arrows, but they are only bitter words, and words are but wind: the curse causeless shall not come. But God has one arrow that will be their death, his curse which is never causeless, and therefore shall come; with it they shall be suddenly wounded, that is, their wound by it will be a surprise upon them, because they were secure and not apprehensive of any danger. 2. Their tongues fell upon him, but God shall make their tongues to fall upon themselves. They do it by the desert of their sin; God does it by the justice of his wrath, Psa 64:8. When God deals with men according to the desert of their tongue-sins, and brings those mischiefs upon them which they have passionately and maliciously imprecated upon others, then he makes their own tongues to fall upon them; and it is weight enough to sink a man to the lowest hell, like a talent of lead. Many have cut their own throats, and many more have damned their own souls, with their tongues, and it will be an aggravation of their condemnation. O Israel! thou hast destroyed thyself, art snared in the words of thy mouth. If thou scornest, thou alone shalt bear it. Those that love cursing, it shall come unto them. Sometimes men's secret wickedness is brought to light by their own confession, and then their own tongue falls upon them.

II.The influence which these judgments should have upon others; for it is done in the open sight of all, Job 34:26.

1.Their neighbours shall shun them and shift for their own safety. They shall flee away, as the men of Israel did from the tents of Korah, Dathan, and Abiram, Num 16:27. Some think this was fulfilled in the death of Saul, when not only his army was dispersed, but the inhabitants of the neighbouring country were so terrified with the fall, not only of their king but of his three sons, that they quitted their cities and fled, Sa1 31:7.

2.Spectators shall reverence the providence of God therein, Psa 64:9. (1.) They shall understand and observe God's hand in all (and, unless we do so, we are not likely to profit by the dispensations of Providence, Hos 14:9): They shall wisely consider his doing. There is need of consideration and serious thought rightly to apprehend the matter of fact, and need of wisdom to put a true interpretation upon it. God's doing is well worth our considering (Ecc 7:13), but it must be considered wisely, that we put not a corrupt gloss upon a pure text. (2.) They shall be affected with a holy awe of God upon the consideration of it. All men (all that have any thing of the reason of a man in them) shall fear and tremble because of God's judgments, Psa 119:120. They shall fear to do the like, fear being found persecutors of God's people. Smite the scorner and the simple shall beware. (3.) They shall declare the work of God. They shall speak to one another and to all about them of the justice of God in punishing persecutors. What we wisely consider ourselves we should wisely declare to others, for their edification and the glory of God. This is the finger of God.

3.Good people shall in a special manner take notice of it, and it shall affect them with a holy pleasure, Psa 64:10. (1.) It shall increase their joy: The righteous shall be glad in the Lord, not glad of the misery and ruin of their fellow-creatures, but glad that God is glorified, and his word fulfilled, and the cause of injured innocency pleaded effectually. (2.) It shall encourage their faith. They shall commit themselves to him in the way of duty and be willing to venture for him with an entire confidence in him. (3.) Their joy and faith shall both express themselves in a holy boasting: All the upright in heart, that keep a good conscience and approve themselves to God, shall glory, not in themselves, but in the favour of God, in his righteousness and goodness, their relation to him and interest in him. Let him that glories glory in the Lord.

So shall they make their own tongue to fall upon themselves,.... The evil things they have wished for, threatened unto, and imprecated on others, shall come upon themselves; the curses they have cursed others with shall come upon themselves; the pit they have dug for others, they fall into. So Haman, to whom some apply the psalm, was hanged on the gallows he made for Mordecai; and the accusers of Daniel, to whom others apply it, were cast into the same den of lions they procured for him; and Babylon, who has been drunk with the blood of the saints, shall have blood given her to drink.

all that see them shall flee away; not being able to help them, nor to bear the horrible sight, and fearing the same judgments should fall on themselves; see Num 16:34. Or, "they shall move themselves" (d); shake their heads in a way of derision, as Jarchi interprets it; or skip for joy, as the word is rendered in Jer 48:27; and then it must be understood of the righteous; who, seeing the vengeance on the wicked, rejoice, as in Psa 52:6; though, as they are afterwards particularly mentioned, others seem to be designed. The word is used for lamenting and bemoaning one's self, in Jer 31:18; and so may be applied to the friends of the wicked lamenting and bemoaning their ruin, and their being bereaved of them, Rev 18:9.

(d) "amovebunt se", Montanus; "commovebuntur", Vatablus.
