4“Let everyone guard against his neighbor;
do not trust any brother,
for every brother deals craftily,
and every friend spreads slander.
5Each one betrays his friend;
no one tells the truth.
They have taught their tongues to lie;
they wear themselves out committing iniquity.
6You dwell in the midst of deception;
in their deceit they refuse to know Me,”
7Therefore this is what the LORD of Hosts says:
“Behold, I will refine them and test them,
for what else can I do
because of the daughter of My people?
8Their tongues are deadly arrows;
they speak deception.
With his mouth a man speaks peace to his neighbor,
but in his heart he sets a trap for him.
9Should I not punish them for these things?
declares the LORD.
Should I not avenge Myself
on such a nation as this?”
— Jeremiah 9:4-9
