The Prayer and accompanying Song are not found in the Hebrew and Aramaic text of the Book of Daniel, nor are they cited in any extant ancient Jewish writings. However, the passage does appear in certain ancient witnesses, notably the Greek, Syriac, and Latin. At the end of the 19th century, M. Gaster identified what appears to be an Aramaic original of the song and another, Bel and Draco, also missing from the canonical book of Daniel. The Aramaic text is part of a collection of ancient Jewish texts compiled by a rabbi of about 14th century, and it is known under the name of The Chronicles of Jerachmeel.
