What are the differences between the Torah and the Old Testament?

Torah is the first 5 books in Bible, written by Moses. Torah is Genesis, Exodus, Leviticus, Numbers, Deuteronomy. The Torah, which means 'Teachings', is the first section of the Jewish Bible which is called the Tanach.

The Old Testament was based on the Tanach, however, it was altered to support the teachings of Christianity. Changes to the text consist of word changes, grammar changes, addition of texts, and a change in the order of books. One of the most glaring changes to the OT was that Daniel was turned into a prophet where he isn't one in the Tanach. The Old Testament is the first half of the Christian Bible.
