JER 34:18

18 Because you have disregarded what I said in my agreement with you, I will do to you just like you did to the calves that you cut in half to show that you would surely do what you solemnly promised that you would do. I will [enable your enemies to] cut you into pieces, you officials of Judah and you officials of Jerusalem, and you officials in the palace, and you priests and all you common people. I will do that because you have disregarded what you solemnly promised [about freeing your slaves].
