2 Chronicles 30:2-5

2The king, his officials, and all the community of Jerusalem decided to celebrate Passover a month later than usual.

3They were unable to celebrate it at the prescribed time because not enough priests could be purified by then, and the people had not yet assembled at Jerusalem.

4This plan for keeping the Passover seemed right to the king and all the people.

5So they sent a proclamation throughout all Israel, from Beersheba in the south to Dan in the north, inviting everyone to come to Jerusalem to celebrate the Passover of the Lord, the God of Israel. The people had not been celebrating it in great numbers as required in the Law.
