Parallel
Jeremiah 9:5
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And they will deceive (note: Or, mock) every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity.
Each one betrays his friend; no one tells the truth. They have taught their tongues to lie; they wear themselves out committing iniquity.
