Matthew Poole and continuators on Jeremiah 31:40

40 And the whole valley of the dead bodies , and of the ashes and all the fields unto the brook of Kidron, unto the corner of the horse-gate towards the east , shall be holy, unto the LORD , it shall not be plucked up, nor thrown down any more for ever .

A valley so called (as some think) from the multitude of Senacherib's Army slain there; or, (as others think) from the Bodies of Malefactors put to death at Golgotha (which was near) cast, or buried there.

So called (as is thought) from the ashes of the sacrifices carried thither.

Some think that the horse-gate had its name from the Kings horses led out at it. The sum is, the whole City shall be built.

All these places shall be parts of the Holy City, and Gods Name shall be sanctified and he shall be worshipped in them all.

And the City for a long time shall abide, and not be plucked up, nor thrown down, for we know after many years it was plucked up by the Romans. If we interpret the word for ever of a perpetuity. The Church of God must here be understood, against which the gates of Hell shall never prevail, as Christ hath promised.
