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 38:6

38:6 So the officials took Jeremiah and put him in the cistern of Malkijah, one of the royal princes, that was in the courtyard of the guardhouse. There was no water in the cistern, only mud. So when they lowered Jeremiah into the cistern with ropes he sank in the mud.
