Hezekiah sent word to all Israel and Judah, and wrote letters also to Ephraim and Manasseh, that they should come to the house of the Lord at Jerusalem, to keep the passover to the Lord the God of Israel.
For the king and his officials and all the assembly in Jerusalem had taken counsel to keep the passover in the second month
(for they could not keep it at its proper time because the priests had not sanctified themselves in sufficient number, nor had the people assembled in Jerusalem).
The plan seemed right to the king and all the assembly.
So they decreed to make a proclamation throughout all Israel, from Beer-sheba to Dan, that the people should come and keep the passover to the Lord the God of Israel, at Jerusalem; for they had not kept it in great numbers as prescribed.
So couriers went throughout all Israel and Judah with letters from the king and his officials, as the king had commanded, saying, "O people of Israel, return to the Lord, the God of Abraham, Isaac, and Israel, so that he may turn again to the remnant of you who have escaped from the hand of the kings of Assyria.
Do not be like your ancestors and your kindred, who were faithless to the Lord God of their ancestors, so that he made them a desolation, as you see.
Do not now be stiff-necked as your ancestors were, but yield yourselves to the Lord and come to his sanctuary, which he has sanctified forever, and serve the Lord your God, so that his fierce anger may turn away from you.
For as you return to the Lord, your kindred and your children will find compassion with their captors, and return to this land. For the Lord your God is gracious and merciful, and will not turn away his face from you, if you return to him."
So the couriers went from city to city through the country of Ephraim and Manasseh, and as far as Zebulun; but they laughed them to scorn, and mocked them.
Only a few from Asher, Manasseh, and Zebulun humbled themselves and came to Jerusalem.
The hand of God was also on Judah to give them one heart to do what the king and the officials commanded by the word of the Lord.
Many people came together in Jerusalem to keep the festival of unleavened bread in the second month, a very large assembly.
They set to work and removed the altars that were in Jerusalem, and all the altars for offering incense they took away and threw into the Wadi Kidron.
They slaughtered the passover lamb on the fourteenth day of the second month. The priests and the Levites were ashamed, and they sanctified themselves and brought burnt offerings into the house of the Lord.
They took their accustomed posts according to the law of Moses the man of God; the priests dashed the blood that they received from the hands of the Levites.
References for 2 Chronicles 30:16
For there were many in the assembly who had not sanctified themselves; therefore the Levites had to slaughter the passover lamb for everyone who was not clean, to make it holy to the Lord.
For a multitude of the people, many of them from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the passover otherwise than as prescribed. But Hezekiah prayed for them, saying, "The good Lord pardon all
who set their hearts to seek God, the Lord the God of their ancestors, even though not in accordance with the sanctuary's rules of cleanness."
