The lip of truth shall be established for ever: but a lying tongue is but for a moment.
The lip of truth shall be established forever. He whose lips speak truth shall be established forever in the favour of God and of man.
But a lying tongue is but for a moment - literally, 'is while I give a wink:' note, Jeremiah 49:19. Liars need to have good memories. A lying tongue soon betrays itself. 'No lie reaches old age,' says Sophocles. A lie is soon or late discovered, and truth emerges.
