Which of the following is NOT one of Jacob's sons?

The correct answer is that David is not one of Jacob's sons. In the context of the Old Testament, Jacob, also known as Israel, had twelve sons, who became the progenitors of the twelve tribes of Israel. These sons include Levi, Reuben, and Simeon, all of whom are integral to the genealogical and historical framework of the Israelites. David, however, is not one of these sons; he is a descendant of Judah, one of Jacob's sons, and is known for becoming the second king of Israel. His lineage is significant in the biblical narrative, particularly regarding the fulfillment of the Davidic covenant and his role in the lineage of Jesus. Thus, while Levi, Reuben, and Simeon are directly linked to Jacob as his sons, David comes from a different generation and line.
