Jeremiah 9:4-7 New Revised Standard Version (NRSV)
4 Beware of your neighbors,
and put no trust in any of your kin;
for all your kin are supplanters,
and every neighbor goes around like a slanderer.
5 They all deceive their neighbors,
and no one speaks the truth;
they have taught their tongues to speak lies;
they commit iniquity and are too weary to repent.
6 Oppression upon oppression, deceit upon deceit!
They refuse to know me, says the Lord.
7 Therefore thus says the Lord of hosts:
I will now refine and test them,
for what else can I do with my sinful people?
