II Chronicles 30:23 Then the whole assembly agreed together to keep the feast for another seven days. So they kept it for another seven days with gladness. 24 For Hezekiah king of Judah gave the assembly 1,000 bulls and 7,000 sheep for offerings, and the princes gave the assembly 1,000 bulls and 10,000 sheep. And the priests consecrated themselves in great numbers. 25 The whole assembly of Judah, and the priests and the Levites, and the whole assembly that came out of Israel, and the sojourners who came out of the land of Israel, and the sojourners who lived in Judah, rejoiced. 26 So there was great joy in Jerusalem, for since the time of Solomon the son of David king of Israel there had been nothing like this in Jerusalem. 27 Then the priests and the Levites arose and blessed the people, and their voice was heard, and their prayer came to his holy habitation in heaven.
We have seen how far downward Judah had spiraled spiritually, having been influenced by the idolatry of the surrounding nations, including Israel. The reign of Hezekiah not only halted that but brought about the restoration of worship in the temple, including the long-lost feast of Passover, which had not been held for generations. It was a glorious celebration. Once phrase which might go unnoticed is extremely significant: and the whole assembly that came out of Israel. Some from the northern kingdom left their false worship to rejoin the spiritual fold of true Israel, just like when it had been one united kingdom. That was monumental. God took notice and heard their voice and prayer. One day all believers of all times will worship that way. What a day that will be!
