Genesis 46:33 Meaning

31And Joseph said unto his brethren, and unto his father's house, I will go up, and shew Pharaoh, and say unto him, My brethren, and my father's house, which were in the land of Canaan, are come unto me;

32And the men are shepherds, for their trade hath been to feed cattle; and they have brought their flocks, and their herds, and all that they have.

33And it shall come to pass, when Pharaoh shall call you, and shall say, What is your occupation?

34That ye shall say, Thy servants' trade hath been about cattle from our youth even until now, both we, and also our fathers: that ye may dwell in the land of Goshen; for every shepherd is an abomination unto the Egyptians.
