The Old Testament is a Christian term for a collection of religious writings of ancient Israel^[1] that form the major and first section of Christian Bibles, in contrast to the Christian New Testament which deals explicitly with the 1st century Christianity. The Hebrew canon approved by Rabbinic Judaism included only certain Hebrew/Aramaic books but not all. Some of these scriptures vary markedly between differing Christian denominations; Protestants accept only the Hebrew Bible‘s canon but divide it into 39 books, while Catholics, the Eastern Orthodox, Coptic and Ethiopian churches recognise a considerably larger collection.^[2]

The books can be broadly divided into the Pentateuch, which tells how God selected Israel to be his chosen people; the history books telling the history of the Israelites from their conquest of Canaan to their defeat and exile in Babylon; the poetic and “wisdom” books dealing, in various forms, with questions of good and evil in the world; and the books of the biblical prophets, warning of the consequences of turning away from God. For the Israelites who were its original authors and readers these books told of their own unique relationship with God and their relationship with proselytes, but the overarching messianic nature of Christianity has led Christians from the very beginning of the faith to see the Old Testament as a preparation for the New Covenant and New Testament.
