Genesis 25:18

And they dwelt from Havilah unto Shur
That is, the posterity of Ishmael, whose country reached from one place to the other; not from India to Chaluza, as the Targums of Jonathan and Jerusalem; but the extent is that vast desert of Arabia, which eastward was called the wilderness of Havilah, and westward the wilderness of Shur; so that they inhabited it from east to west: that [is] before Egypt, as thou goest to Assyria;
which last place was over against Egypt, and bordered on that part where lies the way to the land of Assyria: [and] he died in the presence of all his brethren;
they being present when he died, or in peace with them, in all prosperity along with them: but since his death is spoken of before, and here the situation of his posterity, the words may be read, "it fell ^F25 in the presence of his brethren"; his lot, or the habitation of his posterity fell by lot between his brethren the Egyptians on one side of him, and the Israelites on the other; or between the sons of Keturah on the east, and the posterity of Isaac on the west.
