1 Maccabees 3:46-48

New Revised Standard Version, Anglicised

⁴⁶ Then they gathered together and went to Mizpah, opposite Jerusalem, because Israel formerly had a place of prayer in Mizpah. ⁴⁷ They fasted that day, put on sackcloth and sprinkled ashes on their heads, and tore their clothes. ⁴⁸ And they opened the book of the law to inquire into those matters about which the Gentiles consulted the images of their gods.
