The Book of Lamentations is a collection of poetic laments for the destruction of Jerusalem in 586 BCE. In the Hebrew Bible it appears in the Ketuvim ("Writings") as one of the Five Megillot alongside the Song of Songs, Book of Ruth, Ecclesiastes and the Book of Esther although there is no set order. In the Christian Old Testament it follows the Book of Jeremiah, as the prophet Jeremiah is its traditional author.

The incipit of a text is the first few words of the text, employed as an identifying label. In a musical composition, an incipit is an initial sequence of notes, having the same purpose. The word incipit comes from Latin and means "it begins". Its counterpart taken from the ending of the text is the explicit.
