What does the Bible say about Israel's advantages?

In Romans 9, Paul outlines significant advantages that Israel had, which include their adoption as God's chosen people, the glory that accompanied their journey, the covenants made with the patriarchs, the giving of the law, and the service of God. The adoption speaks to Israel being God's firstborn (Exodus 4:22), while the glory signifies God's manifest presence with them during pivotal moments in their history, such as the Exodus and the construction of the tabernacle. The covenants, particularly the Abrahamic and Davidic covenants, provided the framework for messianic blessings that extend beyond Israel to all nations through Christ. This all showcases the immense privilege and responsibility they held.
