The Introduction to the Book (Ex 1:1-5)
1 Now these are the names of the children of Israel who came to Egypt; each man and his household came with Jacob: 2 Reuben, Simeon, Levi, and Judah; 3 Issachar, Zebulun, and Benjamin; 4 Dan, Naphtali, Gad, and Asher. 5 All those who were descendants of Jacob were seventy persons (for Joseph was in Egypt already).
In Hebrew, Exodus is called “the Book of the Names.” The title comes from the first words of the book: "These are the Names" (Ex 1:1). Exodus begins by reciting the names of the twelve sons of Jacob. It lists the names of the eleven sons of Jacob who took refuge in Egypt during the famine in Genesis. It also mentions Joseph, the son of Jacob who was already in Egypt. As we continue through Exodus, keep in mind that it is called “the Book of Names.” The most important name in this book will be the name of the LORD (Yahweh) that is revealed to Moses in Exodus 3:13-15.
