יהושע יח:ד פירוש: רש״י

For each tribe. For each of the remaining seven tribes.

According to their inheritance. Into seven parts but not equal ones, but according to the tribes appropriate portions— to the large tribe according to its largeness, and to the small tribe according to its smallness, as it is said, ‘To the large [tribe], increase their inheritance.’⁴Bamidbar 26:54.
