2 Chronicles 30:2-5

2For the king had taken counsel, and his princes, and all the congregation in Jerusalem, to keep the passover in the second month.

3For 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.

4And the thing pleased the king and all the congregation.1

5So they established a decree to make proclamation throughout all Israel, from Beer–sheba even to Dan, that they should come to keep the passover unto Yhwh God of Israel at Jerusalem: for they had not done it of a long time in such sort as it was written.
