9 Out of the part of the children of Judah was the inheritance of the children of Simeon; for the portion of the children of Judah was too much for them. Therefore the children of Simeon had inheritance in the midst of their inheritance.

Matthew Henry's Commentary on Joshua 19:9

Commentary on Joshua 19:1-9

(Read Joshua 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.
