John Gill's Bible Commentary Ver. 5. A false witness shall not be unpunished , etc.] 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).
Matthew Henry Commentary
Verses 5 - Those that tell lies in discourse, are in a fair way to be guilty of bearing false-witness.
