Jeremiah 9:7-9

New Revised Standard Version, Anglicised

⁷ Therefore, thus says the Lord of hosts:
I will now refine and test them,
    for what else can I do with my sinful people?^[a]
8 Their tongue is a deadly arrow;
    it speaks deceit through the mouth.
They all speak friendly words to their neighbours,
    but inwardly are planning to lay an ambush.
⁹ Shall I not punish them for these things? says the Lord;
    and shall I not bring retribution
    on a nation such as this?
