Jeremiah 9:3-5 World English Bible (WEB)
3 “They bend their tongue,
as their bow, for falsehood.
They have grown strong in the land,
but not for truth;
for they proceed from evil to evil,
and they don’t know me,” says Yahweh.
4 “Everyone beware of his neighbor,
and don’t trust in any brother;
for every brother will utterly supplant,
and every neighbor will go around like a slanderer.
5 Friends deceive each other,
and will not speak the truth.
They have taught their tongue to speak lies.
They weary themselves commiting iniquity.
