And the second lot came forth to Simeon, even for the tribe of the children of Simeon according to their families: and their inheritance was {a} within the inheritance of the children of Judah.

(a) According to Jacob's prophecy that he would be scattered among the other tribes.

Wesley's Notes

19:1 Within the inheritance of Judah - This was so ordered by God's providence, partly to fulfil that threatning that he would divide and scatter this tribe in Israel, Gen 49:7, which was hereby done in part, because they had no distinct lot, but were as inmates to Judah; partly, because now upon the more exact survey of the land, it appeared, that the part given to Judah did far exceed the proportion which they needed, or which the other tribes could expect. And this was the least of the tribes, Numb 26:14, and therefore fittest to be put within another tribe.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 19

Jos 19:1-9. The Lot of Simeon.

1. the second lot came forth to Simeon-The next lot that was drawn at Shiloh, gave the tribe of Simeon his inheritance within the territory, which had been assigned to that of Judah. The knowledge of Canaan possessed by the Israelites, when the division of the land commenced, was but very general, being derived from the rapid sweep they had made over it during the course of conquest; and it was on the ground of that rough survey alone that the distribution proceeded, by which Judah received an inheritance. Time showed that this territory was too large (Jos 19:9), either for their numbers, however great, to occupy and their arms to defend, or too large in proportion to the allotments of the other tribes. Justice therefore required (what kind and brotherly feeling readily dictated) a modification of their possession; and a part of it was appropriated to Simeon. By thus establishing it within the original domain of another tribe, the prophecy of Jacob in regard to Simeon was fulfilled (Ge 49:7); for from its boundaries being not traced, there is reason to conclude that its people were divided and dispersed among those of Judah; and though one group of its cities named (Jos 19:2-6), gives the idea of a compact district, as it is usually represented by map makers, the other group (Jos 19:7, 8) were situated, two in the south, and two elsewhere, with tracts of the country around them.

Matthew Henry's Concise Commentary

19:1-9 The men of Judah did not oppose taking away the cities within their border, when convinced that they had more than was right. If a true believer has obtained an unintended and improper advantage in any thing, he will give it up without murmuring. Love seeketh not her own, and doth not behave unseemly; it will induce those in whom it richly dwells, to part with their own to supply what is lacking to their brethren.
