The Exodus

The Exodus, more fully The Exodus of Israel out of Egypt, was the departure of the Hebrew slaves from Egypt under the leadership of Moses and Aaron as described in the biblical Book of Exodus. It forms the basis of the Jewish holiday of Passover.

Biblical narrative
The Israelites had moved from the land of Canaan into Egypt when Joseph was prime minister of Egypt. After the death of Joseph and a change in rulership, the Egyptians were now suspicious of the Israelites, particularly because they had begun to greatly increase in number. Therefore they enslaved the Israelites and used them as labor in building projects.
