Simeon's lot was drawn after Judah's, Joseph's, and Benjamin's, because Jacob had put that tribe under disgrace; yet it is put before the two younger sons of Leah and the three sons of the handmaids. Not one person of note, neither judge nor prophet, was of this tribe, that we know of.
I. The situation of their lot was within that of Judah (Jos 19:1) and was taken from it, Jos 19:9. It seems, those that first surveyed the land thought it larger than it was, and that it would have held out to give every tribe in proportion as large a share as they had carved out for Judah; but, upon a more strict enquiry, it was found that it would not reach (Jos 19:9): The part of the children of Judah was too much for them, more than they needed, and more, as it proved, than fell to their share. Yet God did not by the lot lessen it, but left it to their prudence and care afterwards to discover and rectify the mistake, which when they did, 1. The men of Judah did not oppose the taking away of the cities again, which by the first distribution fell within their border, when they were convinced that they had more than their proportion. In all such cases errors must be excepted and a review admitted if there be occasion. Though, in strictness, what fell to their lot was their right against all the world, yet they would not insist upon it when it appeared that another tribe would want what they had to spare. Note, We must look on the things of others, and not on our own only. The abundance of some must supply the wants of others, that there may be somewhat of an equality, for which there may be equity where there is not law. 2. That which was thus taken off from Judah to be put into a new lot Providence directed to the tribe of Simeon, that Jacob's prophecy concerning this tribe might be fulfilled, I will divide them in Jacob. The cities of Simeon were scattered in Judah, with which tribe they were surrounded, except on that side towards the sea. This brought them into a confederacy with the tribe of Judah (Jdg 1:3), and afterwards was a happy occasion of the adherence of many of this tribe to the house of David, at the time of the revolt of the ten tribes to Jeroboam. Ch2 15:9, out of Simeon they fell to Asa in abundance. It is good being in a good neighbourhood.
II. The cities within their lot are here named. Beersheba, or Sheba, for these names seem to refer to the same place, is put first. Ziklag, which we read of in David's story, is one of them. What course they took to enlarge their borders and make room for themselves we find Ch1 4:39, etc.

Baalath-beer - The well of the mistresses. Probably so called from some superstitious or impure worship set up there.

Out of the portion of the children of Judah was the inheritance of the children of Simeon,.... Which is the reason why no description is given of the border of their inheritance, because that is before given in the account of the lot of Judah:

for the part of the children of Judah was too much for them: they had more cities than they could fill with people, and more land than they could cultivate; they had an hundred fourteen cities with their villages:

therefore the children of Simeon had their inheritance within the inheritance of them; the one being a small tribe, and the other large, and for the reasons given; See Gill on Jos 19:1.
