2 Chronicles 30:13-15

Living Bible

¹³ And so it was that a very large crowd assembled at Jerusalem in the month of May for the Passover celebration. ¹⁴ They set to work and destroyed the heathen altars in Jerusalem, and knocked down all the incense altars, and threw them into Kidron Brook.

¹⁵ On the first day of May the people killed their Passover lambs. Then the priests and Levites became ashamed of themselves for not taking a more active part, so they sanctified themselves and brought burnt offerings into the Temple.
