Jacob is the father of the heads of the 12 Tribes of Israel, continuing the lineage from his father Isaac and grandfather Abraham, who were the earlier Patriarchs of the Hebrew Bible.
The father of the heads of the 12 Tribes of Israel is Jacob, who is one of the three Patriarchs in the Hebrew Bible. Jacob is the son of Isaac and the grandson of Abraham, who were patriarchs that preceded him. The story of these patriarchs is integral to the history of the Hebrews, later known as the Israelites, who are depicted in biblical texts such as the book of Genesis and Exodus among others.
The twelve tribes are said to have originated from the twelve sons of Jacob. This formation is crucial to the narrative of the Israelites in the Kingdom of Israel. After leading the Hebrews out of Mesopotamia, Abraham's lineage through Isaac and Jacob became central to the development of these tribes which would later become deeply significant in the religious and cultural history of Judaism and Christianity.
