2 Chronicles 30:2-5
30:2 The king, his officials, and the entire assembly in Jerusalem decided to observe the Passover in the second month.
30:3 They were unable to observe it at the regular time because not enough priests had consecrated themselves and the people had not assembled in Jerusalem.
30:4 The proposal seemed appropriate to the king and the entire assembly.
30:5 So they sent an edict throughout Israel from Beer Sheba to Dan, summoning the people to come and observe a Passover for the Lord God of Israel in Jerusalem, for they had not observed it on a nationwide scale as prescribed in the law.
