'Covenants' in the Bible

To them belongs recognition as God's sons, and they have His glorious Presence and the Covenants, and the giving of the Law, and the Temple service, and the ancient Promises.

All this is allegorical; for the women represent two Covenants. One has its origin on Mount Sinai, and bears children destined for slavery.

At that time you were living apart from Christ, estranged from the Commonwealth of Israel, with no share by birth in the Covenants which are based on the Promises, and you had no hope and no God, in all the world.
