Matthew Poole and continuators on Jeremiah 19:6

6 Therefore behold, the days come, saith the LORD, that this place shall no more be called Tophet, nor the valley of the son of Hinnom, but the valley of slaughter .

For this God by his Prophet threatneth, that this place antiently in Ioshua's time called the valley of the son of Hinnom, and more lately Tophet, from the noise of Drums and Tabrets there, whilst children were burning, should have a new name, and be called the Valley of Slaughter from the multitude of dead bodies, which upon the taking of the City should be slain, and thrown into this Valley. It was expounded chap. 7.32, 33. For they shall bury in Tophet till there be no place; And the carkasses of this people shall be meat for the sowls of the Heaven, and for the beasts of the Earth, and none shall fray them away.
