Matthew Poole and continuators on Joshua 14:4

4 For the children of Joseph were two tribes , Manasseh and Ephraim: therefore they gave no part unto the Levites in the land, save cities to dwell in with their suburbs, for their cattel, and for their substance.

i. e. Had the double Portion, or the Portion of two Tribes, 1 Chron. 5. 1, 2. and therefore though Levi was excluded, there remained nine Tribes and a half, as was said v. 2. to be provided for in Canaan.
