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.

16-18. the priests sprinkled the blood, which they received of the hand of the Levites—This was a deviation from the established rules and practices in presenting the offerings of the temple. The reason was, that many present on the occasion having not sanctified themselves, the Levites slaughtered the paschal victims (see on [465]2Ch 35:5) for everyone that was unclean. At other times the heads of families killed the lambs themselves, the priests receiving the blood from their hands and presenting it on the altar. Multitudes of the Israelites, especially from certain tribes (2Ch 30:18), were in this unsanctified state, and yet they ate the passover—an exceptional feature and one opposed to the law (Nu 9:6); but this exception was allowed in answer to Hezekiah's prayer (2Ch 30:18-20).
