(7) Cursing and deceit.--From the connection of cursing with deceit (comp. Hosea 4:2, "swearing and lying "), we must understand perjury.

Verse 7. - His mouth is full of cursing. (On the prevalence of this evil habit among the powerful in David's time, see Psalm 59:12; Psalm 109:17, 18; 2 Samuel 16:5.) And deceit and fraud; or, guile and extortion (Kay); comp. Psalm 36:3; Psalm 55:11. Under his tongue is mischief and vanity; rather, as in the margin, mischief and iniquity. These are stored "under his tongue," ready for utterance whenever he finds a fit occasion.

10:1-11 God's withdrawings are very grievous to his people, especially in times of trouble. We stand afar off from God by our unbelief, and then complain that God stands afar off from us. Passionate words against bad men do more hurt than good; if we speak of their badness, let it be to the Lord in prayer; he can make them better. The sinner proudly glories in his power and success. Wicked people will not seek after God, that is, will not call upon him. They live without prayer, and that is living without God. They have many thoughts, many objects and devices, but think not of the Lord in any of them; they have no submission to his will, nor aim for his glory. The cause of this is pride. Men think it below them to be religious. They could not break all the laws of justice and goodness toward man, if they had not first shaken off all sense of religion.His mouth is full of cursing,.... Or, "he has filled his mouth with cursing" (e) God and good men, his superiors, himself and others. The word signifies "an oath"; and may design either a profane oath, taking the name of God in vain; or an oath on a civil account, a false oath, taken with a design to defraud and deceive others, as follows, and intends perjury; and this, as applicable to antichrist, regards his mouth speaking great things and blasphemies against God, and uttering curses and anathemas against the saints, Revelation 13:5;

and deceit and fraud; such as flattery and lying, which are both used by him with an intention to impose upon and deceive. The apostle, in Romans 3:14; renders both these words by one, "bitterness"; which may be said of sin in general, which is a very bitter thing; though it is rolled as a sweet morsel in the mouth of a wicked man, yet in the issue it is bitterness to him: and it is applicable to sinful words, which are bitter in their effects to those against whom they are spoken, or who are deceived and imposed upon by them: and, as they refer to antichrist, may have respect to the lies in hypocrisy spoken by him, and to the deceitfulness of unrighteousness, by which he works upon those that perish, 1 Timothy 4:2;

under his tongue is mischief and vanity; alluding to serpents, who have little bags of poison under their teeth; see Psalm 140:3; Kimchi and Ben Melech observe, that the heart is under the tongue, being lower than it, and so denotes the wickedness which that is full of, and devises continually, and is latent in it until discovered; and is mischievous iniquity, injurious to God, and the honour of his law, and to fellow creatures; and especially to the saints, whose persons, characters, and estates, are aimed at; but in the issue it is all vanity, and a fruitless attempt, being blasted by God, and overruled for good to him; see Isaiah 54:17;
