Proverbs 19:5

A false witness shall not be unpunished
He that bears false witness against his neighbour in an open court of judicature; though be may not be detected by men, and so escape the punishment due to such offenders by the laws of God and men; yet God, who knows all hearts and actions, will not suffer him to go with impunity; if not punished in this world, he shall be in the world to come; for bearing false witness, or perjury, is a grievous offence to God; and [he that] speaketh lies shall not escape;
even he that useth himself to lying in private conversation shall not escape the reproach of men; for nothing is more scandalous than lying; nor the wrath of God, such shall have their portion in the lake which burneth with fire and brimstone, ( Revelation 21:8 ) .
