'Covenants' in the Bible

who are Israelites; whose is the adoption, the glory, the covenants, the giving of the law, the service, and the promises;

These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar.

that you were at that time separate from Christ, alienated from the commonwealth of Israel, and strangers from the covenants of the promise, having no hope and without God in the world.
