To the chief Musician, etc. I cannot bring myself to restrict this Psalm to Doeg, as the great body of interpreters do, for the context will clearly show that it speaks of Saul, and of the counselors who ceased not to inflame the king -- himself sufficiently incensed against the life of one who was a saint of God. Being as he was a figure of Christ, we need not wonder that the agents of the devil directed so much of their rage against him. And this is the reason why he animadverts so sharply upon their rancor and treachery. The terms wicked and violent men denote their unwarranted attempts at his destruction without provocation given. He therefore commends his cause to God, as having studied peace with them, as never having injured them, but being the innocent object of their unjust persecution. The same rule must be observed by us all, as it is against violence and wickedness that the help of God is extended. David is not Multiplying mere terms of reproach as men do in their personal disputes, but conciliating God's favor by supplying a proof of his innocence, for he must always be upon the side of good and peaceable men.
Deliver me, O Lord, from the evil man - That is, evidently from some particular man who was endeavoring to injure him; some personal enemy. All the circumstances mentioned agree well with the supposition that Saul is intended.
Preserve me from the violent man - Margin, as in Hebrew, "man of violences." That is, one who has committed violence so often, who has so frequently done wrong, that this may be considered a characteristic of the man. This would apply well to the repeated acts of Saul in persecuting David, and endeavoring to do him injury.
From the evil man - Saul, who was full of envy, jealousy, and cruelty against David, to whom both himself and his kingdom were under the highest obligations, endeavored by every means to destroy him.
"To the chief Musician, A Psalm of David." Deliver me, O LORD, from the evil man: preserve me from the (a) violent man;
(a) Who persecutes me out of malice and without cause.
Deliver me, O Lord, from the evil man,.... Either Saul; so Theodoret; or rather Doeg, according to R. Obadiah: but Jarchi interprets it of Esau; by whom he means Edom, or Rome, or rather the Christians in general. Were his sense confined to the Papists, he might be thought to be much in the right; for this is applicable enough to the man of sin, and his followers: for it may be understood collectively of a body of evil men; all men are evil by nature, their hearts, thoughts, words, works, and ways. David's enemies were evil men; and so were Christ's; as Herod, Judas in particular, and the Jews in general: and such are the enemies of God's people; the world, profane sinners, persecutors, and false teachers; and to be delivered from such is desirable, and to be prayed for, and an happiness when enjoyed; see 2-Thessalonians 3:2;
preserve me from the violent man: or, "the man of violences" (h); of a violent spirit, that breathes out slaughter and death; of a fierce countenance, of blustering words, and furious actions. Such a man was Doeg; who loved evil, and all devouring words, devised mischief, and boasted in it, Psalm 52:1; and Herod, who in his wrath, being disappointed, ordered sit the infants in and about Bethlehem to be slain; and the Jews, who were violently set on the death of Christ, and vehemently desired it: and such are all violent persecutors of the church of God, who clothe themselves with the garment of violence, and drink the wine of it; and to be preserved from such is a great mercy.
(h) "a viro violentiarum", Piscator, Gejerus, Michaelis.
The more danger appears, the more earnest we should be in prayer to God. All are safe whom the Lord protects. If he be for us, who can be against us? We should especially watch and pray, that the Lord would hold up our goings in his ways, that our footsteps slip not. God is as able to keep his people from secret fraud as from open force; and the experience we have had of his power and care, in dangers of one kind, may encourage us to depend upon him in other dangers.
The style of this Psalm resembles those of David in the former part of the book, presenting the usual complaint, prayer, and confident hope of relief. (Psalm 140:1-13)
evil man--Which of David's enemies is meant is not important.
The assimilation of the Nun of the verb נצר is given up, as in Psalm 61:8; Psalm 78:7, and frequently, in order to make the form more full-toned. The relative clause shows that אישׁ חמסים is not intended to be understood exclusively of one person. בּלב strengthens the notion of that which is deeply concealed and premeditated. It is doubtful whether יגוּרוּ signifies to form into troops or to stir up. But from the fact that גּוּר in Psalm 56:7; Psalm 59:4, Isaiah 54:15, signifies not congregare but se congregare, it is to be inferred that גּוּר in the passage before us, like גּרה (or התגּרה in Deuteronomy 2:9, Deuteronomy 2:24), in Syriac and Targumic גּרג, signifies concitare, to excite (cf. שׂוּר together with שׂרה, Hosea 12:4.). In Psalm 140:4 the Psalm coincides with Psalm 64:4; Psalm 58:5. They sharpen their tongue, so that it inflicts a fatal sting like the tongue of a serpent, and under their lips, shooting out from thence, is the poison of the adder (cf. Song 4:11). עכשׁוּב is a ἅπαξ λεγομ. not from כּשׁב (Jesurun, p. 207), but from עכשׁ, Arab. ‛ks and ‛kš, root ‛k (vid., Fleischer on Isaiah 59:5, עכּבישׁ), both of which have the significations of bending, turning, and coiling after the manner of a serpent; the Beth is an organic addition modifying the meaning of the root.
(Note: According to the original Lexicons Arab. ‛ks signifies to bend one's self, to wriggle, to creep sideways like the roots of the vine, in the V form to move one's self like an adder (according to the Ḳamûs) and to walk like a drunken man (according to Neshwn); but Arab. ‛kš signifies to be intertwined, knit or closely united together, said of hairs and of the branches of trees, in the V form to fight hand to hand and to get in among the crowd. The root is apparently expanded into עכשׁוב by an added Beth which serves as a notional speciality, as in Arab. ‛rqûb the convex bend of the steep side of a rock, or in the case of the knee of the hind-legs of animals, and in Arab. charnûb (in the dialect of the country along the coast of Palestine, where the tree is plentiful, in Neshwn churnûb), the horn-like curved pod of the carob-tree (Ceratonia Siliqua), syncopated Arab. charrûb, charrûb (not charûb), from Arab. charn, cogn. qarn, a horn, cf. Arab. chrnâyt, the beak of a bird of prey, Arab. chrnûq, the stork [vid. on Psalm 104:17], Arab. chrnı̂n, the rhinoceros [vid. on Psalm 29:6], Arab. chrnuı̂t, the unicorn [vid. ibid.]. - Wetzstein.)
