Jeremiah 19:7-13
“ ‘ “I will make the counsel of Judah and Jerusalem void in this place. I will cause them to fall by the sword before their enemies, and by the hand of those who seek their life. I will give their dead bodies to be food for the birds of the sky and for the animals of the earth. I will make this city an astonishment and a hissing. Everyone who passes by it will be astonished and hiss because of all its plagues. I will cause them to eat the flesh of their sons and the flesh of their daughters. They will each eat the flesh of his friend in the siege and in the distress, with which their enemies, and those who seek their life, will distress them.” ’
“Then you shall break the container in the sight of the men who go with you, and shall tell them, ‘Yahweh of Armies says: “Even so I will break this people and this city, as one breaks a potter’s vessel, that can’t be made whole again. They will bury in Topheth, until there is no place to bury. This is what I will do to this place,” says Yahweh, “and to its inhabitants, even making this city as Topheth. The houses of Jerusalem, and the houses of the kings of Judah, which are defiled, will be as the place of Topheth, even all the houses on whose roofs they have burned incense to all the army of the sky and have poured out drink offerings to other gods.” ’ ”
If they thought they hated Jeremiah before, God had more for them. We find out from the next passage that Jeremiah is standing right there in Gehenna telling them that they are going to be starved and killed in such numbers that they will not have enough room to bury all the dead in the valley. They are going to be so hungry that they will start eating their own children and friends. Then we find out why God had him bring the pot. He broke it in front of them as an illustration of the fact that they would be so utterly destroyed that they will not be able to be repaired.
This is probably the best reference for what Jesus was communicating when He talked to us about Hell. It’s where the cursed dead were left for the birds. It’s a place of defilement and Jesus added the fact that the real Hell is a place where the worm never dies and the fire never goes out. Why do we have to know this? I think the answer is pretty obvious don’t you? It’s a real place and God doesn’t want man to go there. He made a way for anyone who believes to escape it, but people are ignoring it and building nice parks over the bones of the dead like we see in the Gehenna today. This horrible time was just one of the many that were to happen to Jerusalem after that point in history. We can try to ignore those times and why they happened, or we can learn about them and avoid doing the things that lead to them. This is true for Israel as a nation, and for each of us spiritually.
