Jeremiah 9:3-5

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.

5Everyone 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.
