Joshua 19:9 Meaning and Commentary

Joshua 19:9

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 Joshua 19:1).

Joshua 19:9 In-Context

7 There were also Ain, Rimmon, Ether, and Ashan: four cities, along with the towns around them.
8 This included all the towns around these cities as far as Baalath Beer (or Ramah), in the south. This was the land which the families of the tribe of Simeon received as their possession.
9 Since Judah's assignment was larger than was needed, part of its territory was given to the tribe of Simeon.
10 The third assignment made was for the families of the tribe of Zebulun. The land which they received reached as far as Sarid.
11 From there the border went west to Mareal, touching Dabbesheth and the stream east of Jokneam.
