Jeremiah 9:3-5 NIV

[3] “They make ready their tongue like a bow, to shoot lies; it is not by truth that they triumph in the land. They go from one sin to another; they do not acknowledge me,” declares the LORD. [4] “Beware of your friends; do not trust anyone in your clan. For every one of them is a deceiver, and every friend a slanderer. [5] Friend deceives friend, and no one speaks the truth. They have taught their tongues to lie; they weary themselves with sinning.
