Would Pharaoh do this?

Genesis 45:17 says, “And Pharaoh said unto Joseph, Say unto thy brethren, This do ye; lade your beasts, and go, get you unto the land of Canaan;

45:18 And take your father and your households, and come unto me: and I will give you the good of the land of Egypt, and ye shall eat the fat of the land.

45:19 Now thou art commanded, this do ye; take you wagons out of the land of Egypt for your little ones, and for your wives, and bring your father, and come.

45:20 Also regard not your stuff; for the good of all the land of Egypt is yours.”  The Egyptians are in the middle of year two of a seven-year famine.  Do you believe a Pharaoh would take in a tribe of Hebrews?  I thought even eating with them was an abomination. Genesis 43:32 says, “because the Egyptians might not eat bread with the Hebrews; for that is an abomination unto the Egyptians.”
