David
Psalm 120:3ESV·traditional attribution

What shall be given to you, and what more shall be done to you, you deceitful tongue?

John Calvin Reformed @genevareformer

3. What shall the tongue of deceit give thee? The Psalmist here addresses himself in particular to his traducers. The Prophet aggravates the malice of his enemies by asserting that they were so wickedly inclined as to be driven to evil speaking when they saw no prospect of deriving any advantage from such a course of conduct.

C.H. Spurgeon Reformed Baptist @princeofpreachers

What shall be given unto thee? What is the expected guerdon of slander? It ought to be something great to make it worth while to work in so foul an atmosphere and to ruin one's soul. Could a thousand worlds be bribe enough for such villainous deeds? The liar shall have no welcome recompense: he shall meet with his deserts; but what shall they be?

Matthew Henry Presbyterian @wholebiblehenry

Here is, I. Deliverance from a false tongue obtained by prayer. David records his own experience of this. 1. He was brought into distress, into great distress, by lying lips and a deceitful tongue. There were those that sought his ruin, and had almost effected it, by lying. (1.) By telling lies to him.
