The sections of the New Testament concerning Jesus are called the Gospels and were written about 40 years after the earliest written Christian materials, the letters of Paul, known as the Epistles. It collects 27 books, all originally written in Greek.
The New Testament tells the story of the life of Jesus and the early days of Christianity, most notably Paul’s efforts to spread Jesus’ teaching. The Book of Daniel was written during this period and included in the Septuagint at the last moment, though the text itself claims to have been written sometime around 586 B.C.
