In his theological argument concerning the Abrahamic covenant, Paul almost unconsciously makes an exceedingly strong affirmation of the verbal inspiration of the Old Testament Scriptures, basing his argument not just on one word, but one letter, "seed" instead of "seeds." Thus the promised "Seed" was not the nation Israel, but the one Person who alone could fulfill the great promises made to Abraham, namely, Christ (Genesis 22:17,18).
