Jeremiah 9:3-5

New Catholic Bible

³ Their tongues are like devious weapons,
    bent like a drawn bow.
With falsehood rather than truth
    they have gained power in the land.
They commit one crime after another,
    but they do not acknowledge me, says the Lord.
⁴ Each of you should be on guard against your neighbor
    and place no trust in a brother.
For everyone seeks to supplant his brother, as Jacob did,
    and every friend is a slanderer.
⁵ They all deceive each other;
    no one speaks the truth.
They have trained their tongues in the art of lying;
    immersed in iniquity, they cannot repent.
