2 Chronicles 30:1-6

1 And Hezekiah sendeth unto all Israel and Judah, and also letters he hath written unto Ephraim and Manasseh, to come in to the house of Jehovah in Jerusalem, to make a passover to Jehovah, God of Israel.
2 And the king taketh counsel, and his heads, and all the assembly in Jerusalem, to make the passover in the second month,
3 for they have not been able to make it at that time, for the priests have not sanctified themselves sufficiently, and the people have not been gathered to Jerusalem.
4 And the thing is right in the eyes of the king, and in the eyes of all the assembly,
5 and they establish the thing, to cause to pass over an intimation into all Israel, from Beer-Sheba even unto Dan, to come in to make a passover to Jehovah, God of Israel, in Jerusalem, for not for a long time had they done as it is written.
6 And the runners go with letters from the hand of the king and his heads, into all Israel and Judah, even according to the command of the king, saying, `O sons of Israel, turn back unto Jehovah, God of Abraham, Isaac, and Israel, and He doth turn back unto the escaped part that is left of you from the hand of the kings of Asshur;
