An honest witness tells the truth,
but a false witness tells lies.
The words of the reckless pierce like swords,
but the tongue of the wise brings healing.
Truthful lips endure forever,
but a lying tongue lasts only a moment.
Deceit is in the hearts of those who plot evil,
but those who promote peace have joy.
No harm overtakes the righteous,
but the wicked have their fill of trouble.
The Lord detests lying lips,
but he delights in people who are trustworthy. Proverbs 12:17-22
Here’s a rough paraphrase – If you tell enough lies, eventually you’ll be color blind.
