Adam Clarke on Psalms 140:11

Let not an evil speaker be established - איש לשון ish lashon, "a man of tongue." There is much force in the rendering of this clause in the Chaldee גבר דמשתעי לישן תליתי gebar demishtai lishan telithai, "The man of detraction, or inflammation, with the three-forked tongue." He whose tongue is set on fire from hell; the tale-bearer, slanderer, and dealer in scandal: with the three-forked tongue; wounding three at once: his neiphbour whom he slanders; the person who receives the slander; and himself who deals in it. What a just description of a character which God, angels, and good men must detest! Let not such a one be established in the land; let him be unmasked; let no person trust him; and let all join together to hoot him out of society. "He shall be hunted by the angel of death, and thrust into hell." - Chaldee.
