Jeremiah 9:3-9

“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. “Beware of your friends; do not trust anyone in your clan. For every one of them is a deceiver, and every friend a slanderer. Friend deceives friend, and no one speaks the truth. They have taught their tongues to lie; they weary themselves with sinning. You live in the midst of deception; in their deceit they refuse to acknowledge me,” declares the LORD. Therefore this is what the LORD Almighty says: “See, I will refine and test them, for what else can I do because of the sin of my people? Their tongue is a deadly arrow; it speaks deceitfully. With their mouths they all speak cordially to their neighbors, but in their hearts they set traps for them. Should I not punish them for this?” declares the LORD. “Should I not avenge myself on such a nation as this?”
