Christ the seed, Christ the mediator

¹⁵ My brothers and sisters, let me use a human illustration. When someone makes a covenanted will, nobody sets it aside or adds to it. ¹⁶ Well, the promises were made “to Abraham and his seed,” that is, his family. It doesn’t say “his seeds,” as though referring to several families, but indicates a single family by saying “and to your seed,” meaning the Messiah.

¹⁷ This is what I mean. God made this covenanted will; the law, which came four hundred and thirty years later, can’t undermine it and make the promise null and void.
