Genesis 41:25-27, 33-36

Then Joseph said to Pharaoh, “The [two] dreams are one [and the same and have one interpretation]; God has shown Pharaoh what He is about to do. The seven good cows are seven years, and the seven good ears are seven years; the [two] dreams are one [and the same]. The seven thin and ugly cows that came up after them are seven years; and also the seven thin ears, dried up and scorched by the east wind, they are seven years of famine and hunger.

So now let Pharaoh [prepare ahead and] look for a man discerning and clear-headed and wise, and set him [in charge] over the land of Egypt [as governor under Pharaoh]. Let Pharaoh take action to appoint overseers and officials over the land, and set aside one-fifth [of the produce] of the [entire] land of Egypt in the seven years of abundance. Let them gather [as a tax] all [of the fifth of] the food of these good years that are coming, and store up grain under the direction and authority of Pharaoh, and let them guard the food [in fortified granaries] in the cities. That food shall be put [in storage] as a reserve for the land against the seven years of famine and hunger which will occur in the land of Egypt, so that the land (people) will not be ravaged during the famine.”
