'Covenants' in the Bible

who are Israelites, to whom belongs the adoption as sons, the glory (Shekinah), the [special] covenants [with Abraham, Moses, and David], the giving of the Law, the [system of temple] worship, and the [original] promises.

Now the promises [in the covenants] were decreed to Abraham and to his seed. God does not say, “And to seeds (descendants, heirs),” as if [referring] to many [persons], but as to one, “And to your Seed,” who is [none other than] Christ.

Now these facts are about to be used [by me] as an allegory [that is, I will illustrate by using them]: for these women can represent two covenants: one [covenant originated] from Mount Sinai [where the Law was given] that bears children [destined] for slavery; she is Hagar.

remember that at that time you were separated from Christ [excluded from any relationship with Him], alienated from the commonwealth of Israel, and strangers to the covenants of promise [with no share in the sacred Messianic promise and without knowledge of God’s agreements], having no hope [in His promise] and [living] in the world without God.
