What position did Pharaoh give Joseph?

Answer: Second only to Pharaoh

Pharaoh set Joseph over all the land of Egypt; only with regard to the throne would Pharaoh be greater than him.

“You shall be in charge of my house, and all my people are to obey your commands. Only with regard to the throne will I be greater than you.” Pharaoh also told Joseph, “I hereby place you over all the land of Egypt.””— Genesis 41:40-41 (BSB)
