Jeremiah 7:31-32

31They have built altars in Topheth, in Ben-Hinnom Valley. On those altars, they light fires to burn their sons and daughters as sacrifices. I never commanded them to do that. I never even thought about it.

32So listen to me! The time will soon come when people no longer call those places Topheth or Ben-Hinnom Valley. Instead, they will call it Death Valley. They will bury lots of dead people there. There will be no space left to bury any more people!
