Jeremiah 7:32

“Therefore, behold, the days come, saith the Lord, etc.] And they were coming on apace; a little longer, and they would be come; for it was but a few years after this ere Jerusalem was besieged and taken by the army of the Chaldeans, and the slaughter made after mentioned: that it shall no more be called Tophet: no more be used for such barbarous and idolatrous worship; and no more have its name from such a shocking circumstance: nor the valley of the son of Hinnom; as it had been from the times of Joshua: but the valley of slaughter: or, “of the slain”; as the Targum, Septuagint, Syriac, and Arabic versions; because of the multitude of men that should be killed there, or brought there to be…”

“valley of slaughter--so named because of the great slaughter of the Jews about to take place at Jerusalem: a just retribution of their sin in slaying their children to Moloch in Tophet. no place--no room, namely, to bury in, so many shall be those slain by the Chaldeans (Jer 19:11; Eze 6:5).”

“Jeremiah summons the people to lament over the miserable consequences of their rejection of God. In the valley of Hinnom, where lately they offered their innocents, they shall themselves fall before the enemy in such multitudes that burial shall be impossible, and the beasts of the field unmolested shall prey upon their remains. Jeremiah 7:29 The daughter of Zion, defiled by the presence of enemies in her sanctuary, and rejected of God, must shear off the diadem of her hair, the symbol of her consecration to God, just as the Nazarite, when defiled by contact with a corpse, was to shave his crowned head. Take up a lamentation ... - Or, lift up a “lamentation on the bare hill-sides” Jeremiah…”
