Divrey Hayamim Bais 30:3-5

Orthodox Jewish Bible

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.
