The Old Testament is made up of different genres, but each of these books of the Old Testament work together to tell one narrative. It is not a collection of short stories, but is really one story.
Here's how each book fits into the larger storyline.
Last week, we learnt that through Joseph as a representative of Pharaoh, God saved Jacob's family and brought them out of famine into provision in Goshen. In doing so, God kept his covenant promise to Jacob. In this study, we study this in greater detail, through the genealogy in Genesis 46.
Who are these people corporately? These are the sons of Jacob (also known as Israel when he was renamed in Gen 32).
