2 Chronicles 30:1-5

Hezekiah sent word to all Israel and Judah and also wrote letters to Ephraim and Manasseh, inviting them to come to the temple of the LORD in Jerusalem and celebrate the Passover to the LORD, the God of Israel. The king and his officials and the whole assembly in Jerusalem decided to celebrate the Passover in the second month. They had not been able to celebrate it at the regular time because not enough priests had consecrated themselves and the people had not assembled in Jerusalem. The plan seemed right both to the king and to the whole assembly. They decided to send a proclamation throughout Israel, from Beersheba to Dan, calling the people to come to Jerusalem and celebrate the Passover to the LORD, the God of Israel. It had not been celebrated in large numbers according to what was written.
