What does Jeremiah 19:10 mean?

“‘“I will make the counsel of Judah and Jerusalem void in this place. I will cause them to fall by the sword before their enemies, and by the hand of those who seek their life. I will give their dead bodies to be food for the birds of the sky and for the animals of the earth.

I will make this city an astonishment and a hissing. Everyone who passes by it will be astonished and hiss because of all its plagues.

I will cause them to eat the flesh of their sons and the flesh of their daughters. They will each eat the flesh of his friend in the siege and in the distress, with which their enemies, and those who seek their life, will distress them.”’

and shall tell them, ‘Yahweh of Armies says: “Even so I will break this people and this city, as one breaks a potter’s vessel, that can’t be made whole again. They will bury in Topheth, until there is no place to bury.

Thus will I do to this place,” says Yahweh, “and to its inhabitants, even making this city as Topheth.

The houses of Jerusalem, and the houses of the kings of Judah, which are defiled, will be as the place of Topheth, even all the houses on whose roofs they have burned incense to all the army of the sky, and have poured out drink offerings to other gods.”’”
