Jeremiah 7:31; Jeremiah 7:32

31 They have built the high places of Topheth in the Valley of Ben Hinnom to burn their sons and daughters in the fire—something I did not command, nor did it enter my mind.

32 So beware, the days are coming, declares the LORD, when people will no longer call it Topheth or the Valley of Ben Hinnom, but the Valley of Slaughter, for they will bury the dead in Topheth until there is no more room.
