Jeremiah 31:38-40

38“Behold, the days are coming,” says the Lord, “when the city [of Jerusalem] will be rebuilt for the Lord from the Tower of Hananel to the Corner Gate.

39The measuring line will go out farther straight ahead to the hill Gareb; then it will turn to Goah.

40And the whole valley (Hinnom) of the dead bodies and [the hill] of the ashes [long dumped there from the temple sacrifices], and all the fields as far as the brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to the Lord. It (the city) will not be uprooted or overthrown anymore to the end of the age.”
