Jeremiah 7:32

7:32 So, watch out!” says the Lord. “The time will soon come when people will no longer call those places Topheth or the Valley of Ben Hinnom. But they will call that valley the Valley of Slaughter and they will bury so many people in Topheth they will run out of room.

Jeremiah 19:11

19:11 Tell them the Lord who rules over all says, ‘I will do just as Jeremiah has done. I will smash this nation and this city as though it were a potter’s vessel which is broken beyond repair. The dead will be buried here in Topheth until there is no more room to bury them.’
