What does the Bible say about who are Israelites?

In Romans 9, Paul addresses who the true Israelites are, stating that not all who are descended from Abraham are true Israelites. Paul emphasizes that true Israelites are those whom God has chosen, redeemed, and given special revelation through His Son, Jesus Christ. They are counted as children of God not by natural descent but by God's sovereign election and grace. The privileges and promises of God are intended for these elect individuals, highlighting their unique status in God’s redemptive plan.
