Jeremiah 9:5-9 ASV

5 And they will deceive every one his neighbor, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity. 6 Thy habitation is in the midst of deceit; through deceit they refuse to know me, saith Jehovah. 7 Therefore thus saith Jehovah 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 neighbor with his mouth, but in his heart he layeth wait for him. 9 Shall I not visit them for these things? saith Jehovah; shall not my soul be avenged on such a nation as this?
