Pharaoh had a dream, and this dream was interpreted by Joseph.
According to this interpretation there was to be in Egypt seven years of plenty, followed by seven years of famine. Joseph advised Pharaoh to buy all the surplus of the seven plentiful years and store it up against the years of famine.
Pharaoh appointed Joseph as his minister or agent, and ordered him to buy the grain of the plentiful years.
Then came the famine. The people came to the King for help. He told them to go to Joseph and do as he said.
Joseph sold corn to the Egyptians until all their money was gone—until he had it all.
When the money was gone the people said: "Give us corn and we will give you our cattle."
Joseph let them have corn until all their cattle, their horses and their flocks had been given to him.
Then the people said: "Give us corn and we will give you our lands."
So Joseph let them have corn until all their lands were gone.
But the famine continued, and so the poor wretches sold themselves, and they became the servants of Pharoah.
Then Joseph gave them seed, and made an agreement with them that they should forever give one-fifth of all they raised to Pharaoh.
Who enabled Joseph to interpret the dream of Pharaoh? Jehovah! Did he know at the time that Joseph would use the information thus given to rob and enslave the people of Egypt? Yes. Who produced the famine? Jehovah!
It is perfectly apparent that the Jews did not think of Jehovah as the God of Egypt—the God of all the world. He was their God, and theirs alone. Other nations had gods, but Jehovah was the greatest of all. He hated other nations and other gods, and abhorred all religions except the worship of himself.
