2 Chronicles 30:2

Hezekiah sent to all Israel and Judah, and wrote letters also to Ephraim and Manasseh, that they should come to the LORD’s house at Jerusalem, to keep the Passover to the LORD, the God of Israel.

For they could not keep it at that time, because the priests had not sanctified themselves in sufficient number, and the people had not gathered themselves together to Jerusalem.

The thing was right in the eyes of the king and of all the assembly.

So they established a decree to make proclamation throughout all Israel, from Beersheba even to Dan, that they should come to keep the Passover to the LORD, the God of Israel, at Jerusalem, for they had not kept it in great numbers in the way it is written.
