Jeremiah 9:5-9 English Revised Version (ERV)

5. And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies; they 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 else should I do, because of the daughter of my people?

8. Their tongue is a deadly arrow; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in his heart he layeth wait for him.

9. Shall I not visit them for these things? saith the LORD: shall not my soul be avenged on such a nation as this?
