Major Divisions

The Scriptures are divided into two—the Old and New Testaments. There is a gap of some 400 years between the last book of the Old Testament and the birth of Christ, which marks the beginning of the new.
The Old Testament was written in Hebrew, excepting Ezra 4:8-6:18, 7:12-26, Jer. 10:11, and Dan. 2:4-7:28, which were written in Aramaic. The New Testament was written in Greek.
The arrangement and titles for the books of the Old Testament follow that of the Septuagint (a Greek translation of the Old Testament dating from 280 B.C.). First, the five books of Moses, second, the historical books (Joshua through Esther), third, the poetical books (Job through the Song of Songs), and fourth, the prophetical books (Isaiah through Malachi). Within each group, the books are generally chronological—though the minor prophets (so-called) are grouped together after Daniel.
In the Hebrew Scriptures, the books of the Old Testament are divided into three groups. It is perhaps this arrangement that the Lord Jesus refers to when He says: “These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me” (Luke 24:44). The groupings are firstly the Law (Torah)—the five books of Moses; secondly the Prophets—Joshua, Judges, Samuel, Kings, Isaiah, Jeremiah, Ezekiel, and the twelve minor prophets; and thirdly the Writings—the Psalms, Proverbs, Job, Song of Solomon, Ruth, Lamentations, Ecclesiastes, Esther, Daniel, Ezra, Nehemiah, and Chronicles.
Christ and that which concerns Himself form the grand theme of all Scripture. Another has written, “He is the center of all revelation and the burden of all Scripture”. “Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me” (John 5:39).
