Jeremiah 9:3-5

Amplified Bible

³ 
“They bend their tongue like their bow;
[Their] lies and not truth prevail and grow strong in the land;
For they proceed from evil to evil,
And they do not know and understand and acknowledge Me,” says the Lord.
⁴ 
“Let everyone beware of his neighbor
And do not trust any brother.
For every brother is a supplanter [like Jacob, a deceiver, ready to grab his brother’s heel],
And every neighbor goes around as a slanderer.^(A)
5 
“Everyone deceives and mocks his neighbor
And does not speak the truth.
They have taught their tongue to speak lies;
They exhaust themselves with sin and cruelty.
