2 Chronicles 30:4

2 For the king and his officials and the whole assembly in Jerusalem had decided to keep the Passover in the second month,

3 since they had been unable to observe it at the regular time, because not enough priests had consecrated themselves and the people had not been gathered in Jerusalem.

4 This proposal pleased the king and the whole assembly.

5 So they established a decree to circulate a proclamation throughout Israel, from Beersheba to Dan, that the people should come to keep the Passover of the LORD, the God of Israel, in Jerusalem. For they had not observed it as a nation as prescribed.

6 So the couriers went throughout Israel and Judah with letters from the king and his officials, which read: “Children of Israel, return to the LORD, the God of Abraham, Isaac, and Israel, so that He may return to those of you who remain, who have escaped the grasp of the kings of Assyria.
