Let the lying lips be put to silence - See the notes at Psalm 12:2-3. The lips which speak lies. The reference here is especially to those who had spoken in this manner against the psalmist himself, though he makes the language general, or prays in general that God would silence all liars: a prayer certainly in which all persons may properly join.

Which speak grievous things - Margin, "a hard thing." The Hebrew word - עתק ‛âthâq - means "bold, impudent, wicked." Gesenius, Lexicon. The phrase here means, therefore, to speak wickedly, or to speak in a bold, reckless, impudent manner; that is, without regard to the truth of what is said.

Proudly and contemptuously - Hebrew, in pride and contempt: that is, in a manner which shows that they are proud of themselves and despise others. Slander always perhaps implies this. People are secretly proud of themselves; or they "desire" to cherish an exalted opinion of themselves, and to have others entertain the same opinion of them; and hence, if they cannot exalt themselves by their own merit, as they wish, they endeavor to humble others below their real merit, and to a level lower than themselves, by detraction.

Let the lying lips be put to silence - As to my enemies, persecutors, and slanderers, abate their pride, assuage their malice, and confound their devices. See Jeremiah 18:18.

Let the lying lips be put to silence,.... Being convicted of the lies told by them, and so silenced and confounded; or being cut off and destroyed, as all such will be in the Lord's own time, Psalm 12:3. It is very likely the psalmist may have respect either to Doeg the Edomite, who loved lying rather than righteousness; or to others that were about Saul, who lying said to him that David sought his harm, even to take away his kingdom and his life, Psalm 52:3;

which speak grievous things proudly and contemptuously against the righteous; meaning himself; not that he thought himself righteous in the sight of God by any righteousness of his own, but by the righteousness of Christ imputed to him; see Psalm 143:2. Though he may have regard here to the righteousness of his cause before men, and assert himself righteous, as he might with respect to the "grievous things", the hard and lying speeches, which were spoken against him, in a proud, haughty, and contemptuous manner. And it is no unusual thing for such false charges to be brought against righteous men; nay, such hard speeches were spoken by ungodly men against Jesus Christ the righteous himself, Jde 1:15. The Targum interprets it of "reproaches".

Let the lying lips be put to silence; which speak grievous things proudly and contemptuously against the righteous.

grievous...: Heb. a hard thing

31:9-18 David's troubles made him a man of sorrows. Herein he was a type of Christ, who was acquainted with grief. David acknowledged that his afflictions were merited by his own sins, but Christ suffered for ours. David's friends durst not give him any assistance. Let us not think it strange if thus deserted, but make sure of a Friend in heaven who will not fail. God will be sure to order and dispose all for the best, to all those who commit their spirits also into his hand. The time of life is in God's hands, to lengthen or shorten, make bitter or sweet, according to the counsel of his will. The way of man is not in himself, nor in our friend's hands, nor in our enemies' hands, but in God's. In this faith and confidence he prays that the Lord would save him for his mercies's sake, and not for any merit of his own. He prophesies the silencing of those that reproach and speak evil of the people of God. There is a day coming, when the Lord will execute judgment upon them. In the mean time, we should engage ourselves by well-doing, if possible, to silence the ignorance of foolish men.
