John Chrysostom
Observe the wisdom with which he counsels his brothers, not merely offering casual suggestions, but genuinely desiring to enhance their security and keep them from associating with the Egyptians. The Egyptians held a strong disdain for those who lived as shepherds, and since Joseph's siblings lacked knowledge of Egyptian customs, he advises them to reveal their livelihood at the outset. By doing this, they may, under this reasonable pretense, be distanced from the most suitable land for their well-being, where they could reside safely.
