2 Chronicles 30:21-23

21st Century King James Version

²¹ And the children of Israel who 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.

²² And Hezekiah spoke comfortingly unto all the Levites who taught the good knowledge of the Lord; and they ate throughout the feast seven days, offering peace offerings and making confession to the Lord God of their fathers.

²³ And the whole assembly took counsel to keep another seven days, and they kept another seven days with gladness.
