Jeremiah 9:3-5 New Revised Standard Version, Anglicised (NRSVA)
3 They bend their tongues like bows;
they have grown strong in the land for falsehood, and not for truth;
for they proceed from evil to evil,
and they do not know me, says the Lord.
4 Beware of your neighbours,
and put no trust in any of your kin;
for all your kin are supplanters,
and every neighbour goes around like a slanderer.
5 They all deceive their neighbours,
and no one speaks the truth;
they have taught their tongues to speak lies;
they commit iniquity and are too weary to repent.
