Ephesians 4:22-25
22You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; 23to be made new in the attitude of your minds; 24and to put on the new self, created to be like God in true righteousness and holiness. 25Therefore each of you must put off falsehood and speak truthfully to his neighbour, for we are all members of one body.
Revelation 21:8
8But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars-their place will be in the fiery lake of burning sulfur. This is the second death."
Proverbs 6:16-19
16 There are six things the LORD hates, seven that are detestable to him: 17 haughty eyes, a lying tongue, hands that shed innocent blood, 18 a heart that devises wicked schemes, feet that are quick to rush into evil, 19 a false witness who pours out lies and a man who stirs up dissension among brothers.
Proverbs 19:9
9 A false witness will not go unpunished, and he who pours out lies will perish.
