Final answer:
Joseph saved the Egyptian people from starvation by interpreting Pharaoh's dreams, advising to store grain during seven years of abundance which was then used to feed the population during seven subsequent years of famine. Moses, on the other hand, led the Hebrews out of Egypt after a series of plagues, including the death of the first-born, and is known for the Exodus story.
Step-by-step explanation:
The story of Joseph is quite different from that of Moses. Around 1800 BCE, based on biblical chronology, Joseph's family joined him in Egypt, and his descendants lived there for several generations.
According to the Bible, Joseph saved the Egyptian people from starvation by interpreting the Pharaoh's dreams, which foretold seven years of abundance followed by seven years of famine.
Joseph advised Pharaoh to store grain during the years of abundance. During the famine, this stored grain was used to feed the Egyptians, as well as people from surrounding nations who came to buy grain from Egypt, thus saving them from starvation.
The story of Moses, which often gets conflated with that of Joseph, is about the liberation of the Hebrews from Egyptian bondage. Moses led the Hebrew people out of Egypt after showing Pharaoh a slew of plagues sent by the Hebrew god, including the final plague, which was the death of the first-born of Egypt. The story of the Hebrews' Exodus from Egypt under Moses is detailed in the Bible and marks a foundational moment in the history of the Jewish people.
