2 Chronicles 30:22

And Ezekias encouraged all the Levites, and those that had good understanding of the Lord: and they completely kept the feast of unleavened bread seven days, offering peace-offerings, and confessing to the Lord God of their fathers.

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.

Hezekiah spoke encouragingly to all the Levites who had good understanding in the service of Yahweh. So they ate throughout the feast for the seven days, offering sacrifices of peace offerings and making confession to Yahweh, the God of their fathers.
