'Covenants' in the Bible

who are Israelis. To them belong the adoption, the glory, the covenants, the giving of the Law, the worship, and the promises.

This is being said as an allegory, for these women represent two covenants. The one woman, Hagar, is from Mount Sinai, and her children are born into slavery.

At that time you were without the Messiah, excluded from citizenship in Israel, and strangers to the covenants of promise. You had no hope and were in the world without God.
