Josiah celebrated the Passover to the LORD in Jerusalem, and the Passover lamb was slaughtered on the fourteenth day of the first month. He appointed the priests to their duties and encouraged them in the service of the LORD's temple. He said to the Levites, who instructed all Israel and who had been consecrated to the LORD : "Put the sacred ark in the temple that Solomon son of David king of Israel built. It is not to be carried about on your shoulders. Now serve the LORD your God and his people Israel. Prepare yourselves by families in your divisions, according to the directions written by David king of Israel and by his son Solomon. So they they did it and they celebrated the passover. And it says: So at that time the entire service of the LORD was carried out for the celebration of the Passover and the offering of burnt offerings on the altar of the LORD, as King Josiah had ordered. The Israelites who were present celebrated the Passover at that time and observed the Feast of Unleavened Bread for seven days. The Passover had not been observed like this in Israel since the days of the prophet Samuel; and none of the kings of Israel had ever celebrated such a Passover as did Josiah, with the priests, the Levites and all Judah and Israel who were there with the people of Jerusalem. Since Samuel! That was a long time ago. That must of been an incredible accomplishment.
