16 They stood in their accustomed places, as directed in the Law of Moses the man of God. The priests threw [against the altar] the blood they received from the hand of the Levites.
17 For many were in the assembly who had not sanctified themselves [become clean and free from all sin]. So the Levites had to kill the Passover lambs for all who were not clean, in order to make them holy to the Lord.
18 For a multitude of the people, many from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover otherwise than Moses directed. For Hezekiah had prayed for them, saying, May the good Lord pardon everyone
19 Who sets his heart to seek and yearn for God–the Lord, the God of his fathers–even though not complying with the purification regulations of the sanctuary.
20 And the Lord hearkened to Hezekiah and healed the people.
21 And the Israelites who were in Jerusalem kept the Feast of Unleavened Bread for seven days with great joy. The Levites and priests praised the Lord day by day, singing with instruments of much volume to the Lord.
22 Hezekiah spoke encouragingly to all the Levites who had good understanding in the Lord's work. So the people ate the seven-day appointed feast, offering peace offerings, making confession [and giving thanks] to the Lord, the God of their fathers.
