Since United Bible Societies is inter-confessional, TIPs aims to represent the Christian canon (the books that are considered to be a part of the Bible) of all major confessions. While the canon for the New Testament is identical between all the different branches of the Christian Church, the Old Testament canon is not, and neither are the languages that it is translated from.
The smallest Old Testament canon is that of the Protestant church: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Ruth, 1 Samuel, 2 Samuel, 1 Kings, 2 Kings, 1 Chronicles, 2 Chronicles, Ezra, Nehemiah, Esther, Job, Psalms, Proverbs, Ecclesiastes, Song of Songs, Isaiah, Jeremiah, Lamentations, Ezekiel, Daniel, Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, and Malachi. In the Protestant church these books are translated from their Hebrew versions.
The Catholic church recognizes all of those books as part of its canon, and like the Protestant church translates these from the Hebrew. Their canon also includes: Greek Esther (an expanded version of Esther), Tobit, Judith, 1 Maccabees, 2 Maccabees, Wisdom of Solomon, Sirach, Baruch, Letter of Jeremiah, and Additions to Daniel (Prayer of Azaria [also known as Song of the Three Young Men], Susanna, Bel and the Dragon). The Catholic church refers to these books as “deuterocanonical” and all of them are translated from their Greek versions.
The Eastern and most other Orthodox churches follow the Catholic canon, plus: Prayer of Manasseh, 1 Esdras, 2 Esdras (which is translated from Latin and is not included in the Greek Orthodox church’s canon), 3 Maccabees, and Psalm 151. All of these, as well as all other Old Testament books, are traditionally translated from the Greek.
The Ethiopian and Eritrean Tewahedo churches (part of the Oriental Orthodox church) have an expanded and slightly different canon: instead of 1-3 Maccabees it contains 1-3 Meqabyan (often referred to as Ethiopian Maccabees but containing completely different materials), Enoch (also referred to as 1 Enoch), Jubilees (also known as Lesser Genesis, Leptogenesis, or the Book of Division), and 4 Baruch. These texts are all translated from Ge’ez (Classical Ethiopian).
