The answer is: Lamentations

Jeremiah 52:31 - Lamentations, traditionally attributed to the prophet Jeremiah, poignantly expresses sorrow over the destruction of Jerusalem. This five-chapter book uses acrostic poetry to convey deep grief, mirroring the themes of exile and hope found in other prophetic texts, such as Isaiah and Ezekiel. Lamentations illustrates the balance between mourning and the promise of restoration.
