Jeremiah 7:31; Jeremiah 7:32

31 And they have built the high places of Topheth, which is in the Valley of the Son of Hinnom, to burn their sons and their daughters in the fire, which I did not command, nor did it come into my mind.

32 Therefore, behold, the days are coming, declares the LORD, when it will no more be called Topheth, or the Valley of the Son of Hinnom, but the Valley of Slaughter; for they will bury in Topheth, because there is no room elsewhere.
