16 And they stood in their place after their custom, according to the law of Moses the man of God: the priests sprinkled the blood [receiving it] from the hand of the Levites. 17 For there were many in the congregation that were not hallowed; therefore the Levites had the charge of the slaughtering of the passover-lambs for every one not clean, to hallow them unto Jehovah. 18 For a multitude of the people, many of Ephraim and Manasseh, Issachar and Zebulun, had not cleansed themselves, and they ate the passover otherwise than it was written. But Hezekiah prayed for them saying, Jehovah, who is good, forgive every one

Commentary on 2 Chronicles 30:13-20
(Read 2 Chronicles 30:13-20)
The great thing needful in attendance upon God in solemn ordinances, is, that we make heart-work of it; all is nothing without this. Where this sincerity and fixedness of heart are, there may yet be many things short of the purification of the sanctuary. These defects need pardoning, healing grace; for omissions in duty are sins, as well as omissions of duty. If God should deal with us in strict justice, even as to the very best of our doings, we should be undone. The way to obtain pardon, is to seek it of God by prayer; it must be gotten by petition through the blood of Christ. Yet every defect is sin, and needs forgiveness; and should be matter to humble, but not to discourage us, though nothing can make up for the want of a heart prepared to seek the Lord.
