Ver. 1. And Hezekiah sent to all Israel and Judah
Sent2 Chronicles 30:2

For the king had taken counsel, and his princes, and all the
congregation in Jerusalem
He and his nobles, and the great sanhedrim or senate of the nation, had consulted together: to keep the passover in the second month;
in the month Ijar, as the Targum, because they could not keep it in the first month, as it should have been kept, according to the law of God, for the reasons following.

Divrey Hayamim Bais 30:1 In-Context

1 0 And Chizkiyah sent to kol Yisroel and Yehudah, and wrote iggerot also to Ephrayim and Menasheh, that they should come to the Beis Hashem at Yerushalayim, to keep the Pesach Hashem Elohei Yisroel.

2 For HaMelech had conferred and agreed with his sarim, and kol HaKahal in Yerushalayim, to keep the Pesach in the second month.

3 For they could not keep it at its time, because the Kohanim had not set themselves apart as kodesh in sufficient numbers, neither had HaAm gathered themselves together to Yerushalayim.

4 And the thing pleased HaMelech and kol HaKahal.

5 So they established a decree to make proclamation throughout kol Yisroel, from Beer Sheva even to Dan, that they should come to keep Pesach unto Hashem Elohei Yisroel in Yerushalayim, for not many had kept Pesach as prescribed.
