After Joseph was in prison for two more years, Pharaoh had two dreams which disturbed him. He dreamt of seven lean cows which rose out of the river and devoured seven fat cows; and, of seven withered ears of grain which devoured seven fat ears. Pharaoh's wise men were unable to interpret these dreams, but the chief cup bearer remembered Joseph and spoke of his skill to Pharaoh. Joseph was called for, and interpreted the dreams as foretelling that seven years of abundance would be followed by seven years of famine, and advised Pharaoh to store surplus grain during the years of abundance.

Pharaoh acknowledged that Joseph's proposal to store grain during the abundant period was very wise. So before Joseph was even 30 years old, Pharaoh released him from prison and put him in charge over "all the land of Egypt" as Vizier. The Pharaoh took off his signet ring and put it on Joseph's hand, then clothed him in fine linen and put a gold necklace around his neck. He was then renamed Zaphnath-Paaneah [18] and was given Asenath, the daughter of Potipherah who was the priest of On,[19] to be his wife. During those seven years of abundance, Joseph ensured that the storehouses were full and that all produce was measured until there was so much that it became immeasurable. In the final year of abundance, Asenath bore two children to Joseph: Manasseh and Ephraim. When the famine came, it was so severe that people from surrounding nations "from all over the earth" came to Egypt to buy bread as this nation was the only Kingdom prepared for the seven year drought. The narrative also indicates that they went straight to Joseph or were directed to him, even by Pharaoh himself, so as to buy from him. (Genesis 41:37-57)
The seven year famine became so severe that toward the later period, even Egypt was being strangled. Because the Egyptians had used up all of their money to buy grain in the previous years, there was no more money left. All they had was their livestock and even that dwindled down to nothing. As a last resort, all of the inhabitants of Egypt, less the Egyptian priestly class, sold all of their properties to Joseph for seed. These properties now became the property of the Pharaoh, or in another words, government property. Joseph also set a mandate that because they will be harvesting seed on government property, a fifth of the produce shall go to the Pharaoh. A fifth to the Pharaoh has continued down to at least the days of Moses. (Genesis 47:20-31)
