12 And the west border was to the great sea, and the border [thereof]. This is the border of the children of Judah round about according to their families.

Commentary on Joshua 15:1-12

(Read Joshua 15:1-12)

Joshua allotted to Judah, Ephraim, and the half of Manasseh, their inheritances before they left Gilgal. Afterwards removing to Shiloh, another survey was made, and the other tribes had their portion assigned. In due time all God's people are settled.
