The Book of Odes (Ancient Greek: Ὠδαί), also known as the Biblical Odes, refers to a collection of hymns and prayers referencing the Bible and used as a part of liturgies in some denominations.
The biblical odes form the basis for the Eastern Orthodox canon sung during matins and other services.
The Odes were thought to have existed independently prior to being compiled in to a list.
By the 4th century, Eusebius reported that many hymns and songs had been written.
[1] The earliest surviving collection is found in the fifth century Codex Alexandrinus, which contains 14 odes appended after the Psalms.
