Ezekiel 36:38

Three items in the year all thy males shall appear before the LORD God.

Thrice in the year shall all your men children appear before the LORD God, the God of Israel.

Three times in a year shall all thy males appear before the LORD thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty:

Also at the same time Solomon kept the feast seven days, and all Israel with him, a very great congregation, from the entering in of Hamath unto the river of Egypt.

And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness: and the Levites and the priests praised the LORD day by day, singing with loud instruments unto the LORD. And Hezekiah spake comfortably unto all the Levites that taught the good knowledge of the LORD: and they did eat throughout the feast seven days, offering peace offerings, and making confession to the LORD God of their fathers. And the whole assembly took counsel to keep other seven days: and they kept other seven days with gladness. For Hezekiah king of Judah did give to the congregation a thousand bullocks and seven thousand sheep; and the princes gave to the congregation a thousand bullocks and ten thousand sheep: and a great number of priests sanctified themselves. And all the congregation of Judah, with the priests and the Levites, and all the congregation that came out of Israel, and the strangers that came out of the land of Israel, and that dwelt in Judah, rejoiced. So there was great joy in Jerusalem: for since the time of Solomon the son of David king of Israel there was not the like in Jerusalem. Then the priests the Levites arose and blessed the people: and their voice was heard, and their prayer came up to his holy dwelling place, even unto heaven.

And Josiah gave to the people, of the flock, lambs and kids, all for the passover offerings, for all that were present, to the number of thirty thousand, and three thousand bullocks: these were of the king's substance. And his princes gave willingly unto the people, to the priests, and to the Levites: Hilkiah and Zechariah and Jehiel, rulers of the house of God, gave unto the priests for the passover offerings two thousand and six hundred small cattle and three hundred oxen. Conaniah also, and Shemaiah and Nethaneel, his brethren, and Hashabiah and Jeiel and Jozabad, chief of the Levites, gave unto the Levites for passover offerings five thousand small cattle, and five hundred oxen. So the service was prepared, and the priests stood in their place, and the Levites in their courses, according to the king's commandment. And they killed the passover, and the priests sprinkled the blood from their hands, and the Levites flayed them. And they removed the burnt offerings, that they might give according to the divisions of the families of the people, to offer unto the LORD, as it is written in the book of Moses. And so did they with the oxen. And they roasted the passover with fire according to the ordinance: but the other holy offerings sod they in pots, and in caldrons, and in pans, and divided them speedily among all the people. And afterward they made ready for themselves, and for the priests: because the priests the sons of Aaron were busied in offering of burnt offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests the sons of Aaron. And the singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the porters waited at every gate; they might not depart from their service; for their brethren the Levites prepared for them. So all the service of the LORD was prepared the same day, to keep the passover, and to offer burnt offerings upon the altar of the LORD, according to the commandment of king Josiah. And the children of Israel that were present kept the passover at that time, and the feast of unleavened bread seven days. And there was no passover like to that kept in Israel from the days of Samuel the prophet; neither did all the kings of Israel keep such a passover as Josiah kept, and the priests, and the Levites, and all Judah and Israel that were present, and the inhabitants of Jerusalem. In the eighteenth year of the reign of Josiah was this passover kept.

Thus saith the LORD of hosts; The fast of the fourth month, and the fast of the fifth, and the fast of the seventh, and the fast of the tenth, shall be to the house of Judah joy and gladness, and cheerful feasts; therefore love the truth and peace. Thus saith the LORD of hosts; It shall yet come to pass, that there shall come people, and the inhabitants of many cities: And the inhabitants of one city shall go to another, saying, Let us go speedily to pray before the LORD, and to seek the LORD of hosts: I will go also. Yea, many people and strong nations shall come to seek the LORD of hosts in Jerusalem, and to pray before the LORD. Thus saith the LORD of hosts; In those days it shall come to pass, that ten men shall take hold out of all languages of the nations, even shall take hold of the skirt of him that is a Jew, saying, We will go with you: for we have heard that God is with you.
