Jeremiah 9:4-6

Take ye heed every one of his neighbor, and trust ye not in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders. And they will deceive every one his neighbor, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity. Thy habitation is in the midst of deceit; through deceit they refuse to know me, saith Jehovah.
