Who was Jacob in relation to the Israelites?

Jacob is known as a patriarch in the biblical narrative and is a significant figure in relation to the Israelites. He is the grandson of Abraham and the son of Isaac, making him one of the key ancestors of the Israelite people. Jacob's importance extends beyond just his lineage; he is also central to the stories of the twelve tribes of Israel, as he had twelve sons who became the progenitors of these tribes. His name is later changed to Israel, from which the nation of Israel derives its name. This background illustrates Jacob’s foundational role in the establishment of Israelite identity and heritage, confirming the correctness of the choice that depicts him as a patriarch and grandson of Abraham.
