Explain one similarity and one difference between Christianity and Judaism's holy books. (respond with at least 2-3 sentences)

I will give a few similarities just so you can choose. One is that the Christian Bible's Old Testament is also in Judaism's holy books, as truth. Another is that both Judaism's holy books and Christianity's holy books preach a monotheistic religion. They effectively believe in the same God, just in Judaism, they believe the Messiah is yet to come, whereas Christians believe the Messiah already came, as Jesus.
