Jeremiah 9:3-8 New American Standard Bible (NASB)
3 “They bend their tongue like their bow;
Lies and not truth prevail in the land;
For they proceed from evil to evil,
And they do not know Me,” declares the Lord.
4 “Let everyone be on guard against his neighbor,
And do not trust any brother;
Because every brother deals craftily,
And every neighbor goes about as a slanderer.
5 “Everyone deceives his neighbor
And does not speak the truth,
They have taught their tongue to speak lies;
They weary themselves committing iniquity.
6 “Your dwelling is in the midst of deceit;
Through deceit they refuse to know Me,” declares the Lord.
7 Therefore thus says the Lord of hosts,
“Behold, I will refine them and assay them;
For what else can I do, because of the daughter of My people?
8 “Their tongue is a deadly arrow;
It speaks deceit;
With his mouth one speaks peace to his neighbor,
But inwardly he sets an ambush for him.
