The Old Testament, also known as the Hebrew Bible or Tanakh, comprises 39 books organized into four main sections. The Law (Torah or Pentateuch) includes Genesis through Deuteronomy, traditionally attributed to Moses, covering creation, the patriarchs, the exodus from Egypt, and the covenant at Sinai. The Historical Books (Joshua through Esther) trace Israel's story from conquering Canaan through the monarchy, exile, and return. The Wisdom and Poetry books (Job, Psalms, Proverbs, Ecclesiastes, Song of Solomon) explore human experience, worship, and the fear of the Lord. The Prophets, both Major (Isaiah, Jeremiah, Ezekiel, Daniel) and Minor (Hosea through Malachi), called Israel back to faithfulness and pointed forward to a coming Messiah. Christians read the Old Testament as the first act of a two-act drama, where the Law and Prophets find their fulfilment in Jesus Christ (Matthew 5:17). The old covenant established through Moses at Sinai gives way to the new covenant in Christ's blood, yet the Old Testament remains essential for understanding God's character, His redemptive plan, and the foundations of Christian faith.
