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 21:7
21:7 Then I, the Lord, promise that I will hand over King Zedekiah of Judah, his officials, and any of the people who survive the war, starvation, and disease. I will hand them over to King Nebuchadnezzar of Babylon and to their enemies who want to kill them. He will slaughter them with the sword. He will not show them any mercy, compassion, or pity.’
