The book of Lamentations is counted with the prophetical books in our English Bibles, but in the Jewish scriptures it is one of the writings.

The book was originally written in Hebrew, but the ancient Greek translation known as the Septuagint (abbreviated LXX) is also a very important witness to the text.
