Jeremiah 9:3-5

Authorized (King James) Version

³ And they bend their tongues like their bow for lies:
but they are not valiant for the truth upon the earth;
for they proceed from evil to evil, and they know not me, saith the Lord.
⁴ Take ye heed every one of his neighbour,
and trust ye not in any brother:
for every brother will utterly supplant,
and every neighbour will walk with slanders.
⁵ And they will deceive every one his neighbour,
and will not speak the truth:
they have taught their tongue to speak lies,
and weary themselves to commit iniquity.
