(5-10) They shall divide it into seven parts.--The several tribes were not permitted to choose their own portions. In Numbers 26:54-55, we read: "To many thou shalt give the more inheritance, and to few thou shalt give the less inheritance. . . . notwithstanding the land shall be divided by lot." These words imply that there must be unequal portions of territory for larger and smaller tribes, but that the particular position of each tribe must be settled by the lot, whereof "the whole disposing is of the Lord." We are not told how this rule was carried out in the case of Judah, Ephraim, and Manasseh, who received their inheritance first. Possibly a sufficient extent of territory was surveyed at first to provide three large allotments. The three tribes might then cast lots, first between Judah and Joseph for the northern or southern portions, and then between Ephraim and Manasseh for the two sections of the northern territory. This would carry out the instructions of Numbers 26. But see above (Joshua 15:1).

18:2-10 After a year or more, Joshua blamed their slackness, and told them how to proceed. God, by his grace, has given us a title to a good land, the heavenly Canaan, but we are slack to take possession of it; we enter not into that rest, as we might by faith, and hope, and holy joy. How long shall it be thus with us? How long shall we thus stand in our own light, and forsake our own mercies for lying vanities? Joshua stirs the Israelites up to take possession of their lots. He is ready to do his part, if they will do theirs.And they shall divide it into seven parts,.... According to the number of the seven tribes not yet settled; and this they were to describe and divide was all the land subdued, or not subdued, only the following excepted:

Judah shall abide in their coast on the south; on the south of the land of Canaan, where their lot fell, so that needed not to be measured and described; and this tribe was to retain what they were possessed of, unless it should appear they had too much, and others wanted, and they willing to part with some of it to their brethren, as they afterwards did to the tribes of Simeon and Dan:

and the house of Joseph shall abide in their coast on the north; on the north of the tribe of Judah; not of the land of Canaan, for some other tribes lay more northerly.
