C. F. Keil and Franz Delitzsch on Joshua 18:5-6

Jos 18:5-6

“And divide it into seven parts,” viz., for the purpose of casting lots. Judah, however, was still to remain in its land to the south, and Ephraim in its territory to the north. The seven portions thus obtained they were to bring to Joshua, that he might then cast the lot for the seven tribes “before the Lord,” i.e., before the tabernacle (Jos 19:51).
