We have here some of the genealogies of the tribe of Simeon (though it was not a tribe of great note), especially the princes of that tribe, Ch1 4:38. Of this tribe it is said that they increased greatly, but not like the children of Judah, Ch1 4:27. Those whom God increases ought to be thankful, though they see others that are more increased. Here observe, 1. The cities allotted them (Ch1 4:28), of which see Jos 19:1, etc. When it is said that they were theirs unto the reign of David (Ch1 4:31) intimation is given that when the ten tribes revolted from the house of David many of the Simeonites quitted these cities, because they lay within Judah, and seated themselves elsewhere. 2. The ground they got elsewhere. When those of this tribe that revolted from the house of David were carried captive with the rest into Assyria those that adhered to Judah were remarkably owned of God and prospered in their endeavours to enlarge their coasts. It was in the days of Hezekiah that a generation of Simeonites, whose tribe had long crouched and truckled, was animated to make these bold efforts. (1.) Some of them attacked a place in Arabia, as it should seem, called the entrance of Gedor, inhabited by the posterity of accursed Ham (Ch1 4:40), made themselves masters of it, and dwelt there. This adds to the glory of Hezekiah's pious reign, that, as his kingdom in general prospered, so did particular families. It is said that they found fat pastures, and yet the land was quiet; even when the kings of Assyria were giving disturbance to all their neighbours this land escaped their alarms. The inhabitants being shepherds, who molested none, were not themselves molested, till the Simeonites came and drove them out and succeeded them, not only in the plenty, but in the peace, of their land. Those who dwell (as we do) in a fruitful country, and whose land is wide, and quiet, and peaceable, have reason to own themselves indebted to that God who appoints the bounds of our habitation. (2.) Others of them, to the number of 500, under the command of four brethren here named, made a descent upon Mount Seir, and smote the remainder of the devoted Amalekites, and took possession of their country, Ch1 4:42, Ch1 4:43. Now the curses on Ham and Amalek had a further accomplishment, when they seemed dormant, if not dead; as had also the curse on Simeon, that he should be divided and scattered (Gen 49:7): yet to him it was turned into a blessing, for the families of Simeon, which thus transplanted themselves into those distant countries, are said to dwell there unto this day (Ch1 4:43), by which it should seem they escaped the calamities of the captivity. Providence sometimes sends those out of trouble that are designed for preservation.

Neither did all their family multiply - In Num 1:23 the number of all the families of Simeon was fifty-nine thousand three hundred; and that of Judah was, Num 1:27, not less than seventy-four thousand six hundred. When the next census was made, Num. 26, the tribe of Judah amounted to seventy-six thousand five hundred, an increase of one thousand nine hundred; while the tribe of Simeon amounted only to twenty-two thousand two hundred, a decrease of thirty-seven thousand one hundred. It was at that time the smallest tribe in Israel.

And they dwelt at Beersheba,.... posterity of Simeon; and this and the other places of their habitation are mentioned in the same order, and with very little variation of names to the end of Ch1 4:31, as in Jos 19:2 and here, at Ch1 4:31 it is added:

these were their cities unto the reign of David; when, according to Kimchi, and other Jewish writers, he expelled them from thence, and restored them to the tribe of Judah.

his brethren had not many children--(see Num 1:22; Num 26:14).
