Jeremiah 9:3-5

“And like their bow they have bent their tongues for lies. They are not valiant for the truth on the earth. For they proceed from evil to evil, And they do not know Me,” says the LORD. “Everyone take heed to his neighbor, And do not trust any brother; For every brother will utterly supplant, And every neighbor will walk with slanderers. Everyone will deceive his neighbor, And will not speak the truth; They have taught their tongue to speak lies; They weary themselves to commit iniquity.
