How do we know that God chose the twelve tribes of Israel?

God's selection of the twelve tribes of Israel begins with His covenant with Abraham, as noted in Genesis 12:3, where God promises blessings to all families of the earth through Abraham’s lineage. The significance of Israel’s twelve sons is highlighted in their role in God's redemptive plan, showcasing God's sovereignty in choosing a people for Himself. The New Testament further clarifies this relationship, particularly in Romans 9:6-8, affirming that not all descendants of Abraham are considered children of God, but rather those chosen by faith.
