Now the promises (covenants, agreements) were decreed and made to Abraham and his Seed (his Offspring, his Heir). He [God] does not say, And to seeds (descendants, heirs), as if referring to many persons, but, And to your Seed (your Descendant, your Heir), obviously referring to one individual, Who is [none other than] Christ (the Messiah). [Gen. 13:15; 17:8.]
