Text: (Genesis 41:14-46 KJV).
Then Pharaoh sent and called Joseph, and they brought him hastily out of the dungeon: and he shaved himself, and changed his raiment, and came in unto Pharaoh. And Pharaoh said unto Joseph, I have dreamed a dream, and there is none that can interpret it: and I have heard say of thee, that thou canst understand a dream to interpret it. And Joseph answered Pharaoh, saying, It is not in me: God shall give Pharaoh an answer of peace. And Pharaoh said unto Joseph, In my dream, behold, I stood upon the bank of the river: And, behold, there came up out of the river seven kine, fatfleshed and well favoured; and they fed in a meadow: And, behold, seven other kine came up after them, poor and very ill favoured and leanfleshed, such as I never saw in all the land of Egypt for badness: And the lean and the ill favoured kine did eat up the first seven fat kine: And when they had eaten them up, it could not be known that they had eaten them; but they were still ill favoured, as at the beginning. So I awoke. And I saw in my dream, and, behold, seven ears came up in one stalk, full and good: And, behold, seven ears, withered, thin, and blasted with the east wind, sprung up after them: And the thin ears devoured the seven good ears: and I told this unto the magicians; but there was none that could declare it to me. And Joseph said unto Pharaoh, The dream of Pharaoh is one: God hath shewed Pharaoh what he is about to do. The seven good kine are seven years; and the seven good ears are seven years: the dream is one. And the seven thin and ill favoured kine that came up after them are seven years; and the seven empty ears blasted with the east wind shall be seven years of famine. This is the thing which I have spoken unto Pharaoh: What God is about to do he sheweth unto Pharaoh. Behold, there come seven years of great plenty throughout all the land of Egypt: And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt; and the famine shall consume the land; And the plenty shall not be known in the land by reason of that famine following; for it shall be very grievous. And for that the dream was doubled unto Pharaoh twice; it is because the thing is established by God, and God will shortly bring it to pass. Now therefore let Pharaoh look out a man discreet and wise, and set him over the land of Egypt. Let Pharaoh do this, and let him appoint officers over the land, and take up the fifth part of the land of Egypt in the seven plenteous years. And let them gather all the food of those good years that come, and lay up corn under the hand of Pharaoh, and let them keep food in the cities. And that food shall be for store to the land against the seven years of famine, which shall be in the land of Egypt; that the land perish not through the famine. And the thing was good in the eyes of Pharaoh, and in the eyes of all his servants. And Pharaoh said unto his servants, Can we find such a one as this is, a man in whom the Spirit of God is? And Pharaoh said unto Joseph, Forasmuch as God hath shewed thee all this, there is none so discreet and wise as thou art: Thou shalt be over my house, and according unto thy word shall all my people be ruled: only in the throne will I be greater than thou. And Pharaoh said unto Joseph, See, I have set thee over all the land of Egypt. And Pharaoh took off his ring from his hand, and put it upon Joseph's hand, and arrayed him in vestures of fine linen, and put a gold chain about his neck; And he made him to ride in the second chariot which he had; and they cried before him, Bow the knee: and he made him ruler over all the land of Egypt. And Pharaoh said unto Joseph, I am Pharaoh, and without thee shall no man lift up his hand or foot in all the land of Egypt. And Pharaoh called Joseph's name Zaphenath–paneah; and he gave him to wife Asenath the daughter of Poti–phera priest of On. And Joseph went out over all the land of Egypt. And Joseph was thirty years old when he stood before Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh, and went throughout all the land of Egypt. (Genesis 41:14-46 KJV).
