2 Chronicles 30:13-15

13A very large assembly of people was gathered in Jerusalem to observe the Festival of Unleavened Bread in the second month.

14They proceeded to take away the altars that were in Jerusalem, and they took away the incense altars and threw them into the Kidron Valley.

15They slaughtered the Passover lamb on the fourteenth day of the second month. The priests and Levites were ashamed, and they consecrated themselves and brought burnt offerings to the Lord’s temple.
