Genesis 46:9 lists the sons of Reuben—Hanoch, Phallu, Hezron, and Carmi—as part of the record of Jacob’s (Israel’s) family who went down to Egypt. This verse is part of a genealogy showing the direct descendants of Jacob’s oldest son, Reuben.
In the story, Jacob and his family are moving to Egypt during a famine, where Joseph has become a powerful leader. The verse is part of a careful listing of each son and grandson, emphasizing the family’s size and identity as they relocate. This genealogy helps set the stage for the later growth of the Israelites in Egypt.
