The people of Judah have done evil by setting their abominations in the house bearing God's name and defiling it.
This verse opens the final section with the desecration of the temple.
30For the people of Judah have done evil in My sight, declares the LORD. They have set up their abominations in the house that bears My Name, and so have defiled it. 31They have built the high places of Topheth in the Valley of Ben-hinnom so they could burn their sons and daughters in the fire — something I never commanded, nor did it even enter My mind. 32So behold, the days are coming, declares the LORD, when this place will no longer be called Topheth and the Valley of Ben-hinnom, but the Valley of Slaughter. For they will bury the dead in Topheth until there is no more room. 33The corpses of this people will become food for the birds of the air and the beasts of the earth, and there will be no one to scare them away. 34I will remove from the cities of Judah and the streets of Jerusalem the sounds of joy and gladness and the voices of the bride and bridegroom, for the land will become a wasteland.”
