Truthful lips endure forever, but a lying tongue lasts only a moment.
In context
17Whoever breathes out faithfulness declares what is right, but a false witness, deceit. 18There is one whose rash words are like sword thrusts, but the tongue of the wise brings healing. 19Truthful lips endure forever, but a lying tongue lasts only a moment. 20Deceit is in the heart of those who plot evil, but those who counsel peace have joy. 21No harm befalls the righteous, but the wicked are filled with evil.
