Old Testament
The Old Testament in Western Christianity, refers to the books that form the first of the two-part Christian Bible. These works correspond to the Hebrew Bible (Tanakh), with some variations and additions. In the Eastern Orthodox Church the comparable texts are known as the Septuagint, from the original Greek translation of the Hebrew scriptures. The term "Old Testament" itself is credited to Tertullian, who used the Latin vetus testamentum in the second century.
Most scholars agree that the Hebrew Bible was composed and compiled between the 12th and the 2nd century BC, before Jesus' birth. Jesus and his disciples based their teachings on them.
