Genesis 46:34
That 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.
Cross-reference
In Genesis 46:32, they are described as shepherds with livestock — here they are instructed to tell Pharaoh they have always been keepers of livestock.
In Genesis 45:10, Joseph promises Goshen as their dwelling; 46:34 then explains the reason—shepherds are abominable to Egyptians.
In Genesis 47:1, Joseph reports to Pharaoh that his family is in Goshen—the fulfillment of the plan laid out in 46:34.
In Genesis 47:3, the brothers declare 'your servants are shepherds' exactly as Joseph instructed in 46:34—direct narrative fulfillment.
In Genesis 47:4, the brothers ask to dwell in Goshen, the region Joseph chose because Egyptians detest shepherds (46:34).
In Genesis 43:32, the same 'abomination to the Egyptians' phrase describes why Egyptians couldn't eat with Hebrews—reinforcing the cultural barrier that Joseph exploits in 46:34.
Genesis 37:12 shows the brothers shepherding their father's flock — consistent with their lifelong claim of being shepherds here.
In Exodus 8:26, Moses uses the same 'abomination to the Egyptians' logic to refuse sacrificing in Egypt—showing it was a consistent cultural taboo.
