In Genesis 41-42, Joseph's gift of dream interpretation propels him to prominence. Pharaoh experiences two troubling dreams that none can interpret. The chief cupbearer, recalling his oversight, mentions Joseph. Brought before Pharaoh, Joseph interprets the dreams as seven years of plenty followed by seven years of famine and advises strategic grain storage. Impressed, Pharaoh appoints Joseph as Egypt's second-in-command. During the years of plenty, Joseph oversees grain collection, and as famine hits, people from surrounding regions come to Egypt for food, including Jacob's sons. In Genesis 42, the brothers face Joseph, not recognizing him. Joseph, however, recognizes them and tests their integrity by accusing them of being spies. He demands they bring Benjamin, the youngest, to prove their honesty. Leaving Simeon as collateral, the brothers return to Canaan, unaware Joseph secretly returned their money in their sacks.
