And the border went up by the valley of the son of Hinnom,.... Which belonged to a man of that name formerly; and was near Jerusalem, placed by Jerom (l) to the east of it; but Reland (m) rather thinks it is to the south. It was infamous for the sacrifices of children to Moloch in it, by burning them, or causing them to pass through fire: hence, in allusion to it, hell fire is often in the New Testament called "Geenna", Mat 5:22 Luk 12:5; this border from the salt sea, and from Jordan, is all along said to "go up", because from hence to Jerusalem was an ascent, that lying on higher ground: unto the south side of the Jebusite; of the place the Jebusite inhabited: the same is Jerusalem; which was formerly called Jebus, from the inhabitants of it; yea, Jebusi, as here, and so may intend not the inhabitants, but the place, see Jos 18:28; and here the Jebusites lived, at least in some part of it, until the time of David, Sa2 5:6, and the border went up to the top of the mountain that lieth before the valley of Hinnom westward: which is generally supposed to be the mount Moriah: which is at the end of the valley of the giants, northward: the valley of Rephaim, as it is called Sa2 5:18, and here Mount Moriah, as it was to the west of the valley of Hinnom, it was to the north of the valley of Rephaim; which valley, as Josephus (n) says, was not far from Jerusalem, twenty furlongs from it. Some late travellers (o) tell us it lies in the way from Jerusalem to Bethlehem, and is not above two hours' ride from the former. From this account it appears, as Jarchi remarks, that Jerusalem was not within the line, and was not in the border of Judah, but of Benjamin, which tribe lay to the north of Judah: it seems indeed to have been one part of it in the tribe of Judah, and the other in the tribe of Benjamin; though the Jews frequently say it did not belong to either tribe.
