What does Psalm 12:3 mean?

David is embroiled in what seems like an entirely dishonest, completely ungodly culture (Psalm 12:1–2). This is probably a deliberate exaggeration, known as hyperbole, something seen elsewhere in the Bible (Psalm 18:34; Matthew 7:3; Proverbs 4:16). This also echoes other Old Testament complaints offered towards God about the prevalence of evil (Habakkuk 2:1–4; Psalms 22:1). Scripture gives no details about exactly what prompted David to write this psalm. He prays for the Lord to silence the false talkers, who flatter and boast. These evil ones are assured of their sins, thinking there will be no consequences (Psalm 12:4).

Every generation has an abundance of "big talkers." They use arrogance, bragging, smooth talk, and lying compliments to deceive and dominate. Daniel 7:23–26 refers to an evil figure who will come to power in the end-times tribulation period. He speaks words against God and persecutes God's people (Daniel 7:25). But after three and a half years, this big-talking leader faces sudden judgment. He and his kingdom will be consumed and destroyed (Daniel 7:26). This end-time antichrist and his allies take their lead from the old serpent, the Devil, whose evil words seduced Eve. She fell for his lies and denial of God's prediction of death for disobeying His will (Genesis 3:1–6). Someday, however, an angel will descend from heaven, seize the Devil, bind him for a thousand years, and cast him into the bottomless pit (Revelation 20:1–3). Ultimately, the Devil who deceives the nations will spend eternity in the lake of fire (Revelation 20:10).
