Exodus Chapter 13: Yahuah commands the Israelites to consecrate every firstborn male to Him,

both human and animal, as a remembrance of the final plague that led to their freedom. The chapter also details the observance of the Feast of Unleavened Bread, symbolizing the Israelites' haste in leaving Egypt. Moshe leads the Israelites out of Egypt, carrying Joseph’s bones with them, and they are guided by a pillar of cloud by day and a pillar of fire by night.
