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. 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. At the king's command, couriers went throughout Israel and Judah with letters from the king and from his officials.
The couriers went from town to town in Ephraim and Manasseh, as far as Zebulun, but the people scorned and ridiculed them. Nevertheless, some men of Asher, Manasseh and Zebulun humbled themselves and went to Jerusalem. The Israelites who were present in Jerusalem celebrated the Feast of Unleavened Bread for seven days with great rejoicing, while the Levites and priests sang to the LORD every day, accompanied by the LORD's instruments of praise. Hezekiah spoke encouragingly to all the Levites, who showed good understanding of the service of the LORD. For the seven days they ate their assigned portion and offered fellowship offerings and praised the LORD, the God of their fathers. The whole assembly then agreed to celebrate the festival seven more days; so for another seven days they celebrated joyfully. The priests and the Levites stood to bless the people, and God heard them, for their prayer reached heaven, his holy dwelling place.
Whoa, that would of been amazing! Then they decided to celebrate for 7 more days! wow!!
