Jeremiah 9:8

⁶ You dwell in the midst of deception; in their deceit they refuse to know Me,” declares the LORD.

⁷ Therefore this is what the LORD of Hosts says: “Behold, I will refine them and test them, for what else can I do because of the daughter of My people?

Their tongues are deadly arrows; they speak deception. With his mouth a man speaks peace to his neighbor, but in his heart he sets a trap for him.

⁹ Should I not punish them for these things? declares the LORD. Should I not avenge Myself on such a nation as this?”

¹⁰ I will take up a weeping and wailing for the mountains, a dirge over the wilderness pasture, for they have been scorched so no one passes through, and the lowing of cattle is not heard. Both the birds of the air and the beasts have fled; they have gone away.

Do read the surrounding verses too, because the context often says more than a single verse.
