If you enjoy a challenge, I recommend this book: Mind the Gap: How the Jewish Writings
between the Old and New Testament Help Us Understand Jesus, by Matthias
Henze. Fortress Press.
One example from the book:
While there are several individuals in the Bible who are
said to be anointed, the word “messiah” or “anointed one” is never used in the
Old Testament to designate a future anointed redeemer figure.
In other words, there are no texts in the Old Testament that
know of the concept of a messiah as an awaited agent of God, a descendant of
David who will appear to reign over a restored kingdom of Israel at the end of
time. That concept of a future messiah was only developed in later times, after
the Old Testament.
There are several “messiahs” in the Old Testament, to be
sure, but they are not divine figures
of the end of time. They are the kings, priests, and prophets of ancient
Israel.
And yet, when Andrew tells his brother Simon Peter, “We have
found the Messiah,” or when the Samaritan woman declares, “I know that the
Messiah is coming,” they are not referring to an earthly king, priest, or
prophet. They are expressing the hope for a future redeemer figure, the messiah
of the end time. We find that concept develop in the literature that was
written during the gap years in between the Old and the New Testament.
There are no texts in the Old Testament that speak of a future messianic
figure of the end time. (Henze, pages 58-59)
