2 Chronicles 30:4

וַיִּוָּעַץ הַמֶּלֶךְ וְשָׂרָיו וְכָל־הַקָּהָל בִּירוּשָׁלִָם לַעֲשׂוֹת הַפֶּסַח בַּחֹדֶשׁ הַשֵּׁנִֽי

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

כִּי לֹא יָכְלוּ לַעֲשֹׂתוֹ בָּעֵת הַהִיא כִּי הַכֹּהֲנִים לֹֽא־הִתְקַדְּשׁוּ לְמַ דַּי וְהָעָם לֹא־נֶאֶסְפוּ לִֽירוּשָׁלִָֽם

For they could not keep it at that time, because the priests had not sanctified themselves in sufficient number, neither had the people gathered themselves together to Jerusalem.

וַיַּֽעֲמִידוּ דָבָר לְהַעֲבִיר קוֹל בְּכָל־יִשְׂרָאֵל מִבְּאֵֽר־שֶׁבַע וְעַד־דָּן לָבוֹא לַעֲשׂוֹת פֶּסַח לַיהוָה אֱלֹהֵֽי־יִשְׂרָאֵל בִּירוּשָׁלִָם כִּי לֹא לָרֹב עָשׂוּ כַּכָּתֽוּב

So 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 the LORD, the God of Israel, at Jerusalem; for they had not kept it in great numbers according as it is written.

וַיֵּלְכוּ הָרָצִים בָּֽאִגְּרוֹת מִיַּד הַמֶּלֶךְ וְשָׂרָיו בְּכָל־יִשְׂרָאֵל וִֽיהוּדָה וּכְמִצְוַת הַמֶּלֶךְ לֵאמֹר בְּנֵי יִשְׂרָאֵל שׁוּבוּ אֶל־יְהוָה אֱלֹהֵי אַבְרָהָם יִצְחָק וְיִשְׂרָאֵל וְיָשֹׁב אֶל־הַפְּלֵיטָה הַנִּשְׁאֶרֶת לָכֶם מִכַּף מַלְכֵי אַשּֽׁוּר

So the posts went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying: ‘Ye children of Israel, turn back unto the LORD, the God of Abraham, Isaac, and Israel, that He may return to the remnant that are escaped of you out of the hand of the kings of Assyria.
