Jeremiah 9:5-8 King James Version (KJV)

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.

6. Thine habitation is in the midst of deceit; through deceit they refuse to know me, saith the Lord.

7. Therefore thus saith the Lord of hosts, Behold, I will melt them, and try them; for how shall I do for the daughter of my people?

8. Their tongue is as an arrow shot out; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait.
