Isaiah 30:33

For Topheth [in Hinnom] has long been ready; Indeed, it has been prepared for the [Assyrian] king. He has made it deep and wide, A pit of fire with plenty of wood; The breath of the LORD, like a river of brimstone (blazing sulfur), kindles and fans it. [Jer 7:31, 32; Matt 5:22; 25:41]
