וְהָאֲנָשִׁים֙ רֹ֣עֵי צֹ֔אן כִּֽי־אַנְשֵׁ֥י מִקְנֶ֖ה הָי֑וּ וְצֹאנָ֧ם וּבְקָרָ֛ם וְכָל־אֲשֶׁ֥ר לָהֶ֖ם הֵבִֽיאוּ׃
그들은 목자라 목축으로 업을 삼으므로 그 양과 소와 모든 소유를 이끌고 왔나이다 하리니
Ramban on Genesis
AND THE MEN ARE SHEPHERDS, FOR THEY HAVE BEEN KEEPERS OF CATTLE. Joseph told them that they are shepherds but that they do not tend to the cattle of others because even with respect to their own cattle, they have servants and attendants to pasture them. It is only that their wealth consists of cattle. This is the sense of the expression, they have been keepers of cattle, and had wealth, and a very great household231Job 1:3. by virtue of the great multitude of cattle which they possessed. It was Joseph’s intention to mention them in an honorable way.
Tur HaArokh
והאנשים רועי צאן, “and the men are shepherds by vocation.” He did not mean to say that the brothers themselves were shepherds, but that they were experts in sheep and cattle raising as their vast wealth consisted primarily of flocks and herds, while their servants did the actual minding of the beasts.
