2 Chronicles 30:4

For the king had taken counsel, and his princes, and all the congregation in Jerusalem, to keep the passover in the second month.

For they could not keep it at that time, because the priests had not sanctified themselves sufficiently, neither had the people gathered themselves together to Jerusalem.

So they established a decree to make proclamation throughout all Israel, from Beersheba even to Dan, that they should come to keep the passover unto the LORD God of Israel at Jerusalem: for they had not done [it] of a long [time in such sort] as it was written.

So the posts went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying, Ye children of Israel, turn again unto the LORD God of Abraham, Isaac, and Israel, and he will return to the remnant of you, that are escaped out of the hand of the kings of Assyria.
