(19) That prepareth.--Hath directed. The division of verses here is obviously incorrect. (The mistake was doubtless caused by the omission of the relative in the Hebrew between kol, "every one," and l?b?bo h?kin, "his heart he hath directed." The construction is parallel to that in 1Chronicles 15:12, "unto the place that I have prepared for it;" so LXX.) The prayer is, "Jehovah the Good atone for every one who hath directed his heart to seek the true God, even Jehovah, the God of his fathers, albeit not (literally, and not) according to the holy purifying"--i.e., although he hath not rigorously observed the law of purification.

Purification of the sanctuary.--Or, holy purification: a phrase only found here (comp. 1Chronicles 23:28).

The prayer evinces a preference of spiritual sincerity to mere literal observance of legal prescriptions, which is all the more remarkable as occurring in a writer whose principal aim is to foster a due reverence for the external ordinances and traditional customs of religion.

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.That prepareth his heart to seek God, the Lord God of his fathers,.... Who was heartily desirous of worshipping God, and observing his ordinances, which had been enjoined their fathers, and they had kept; though Aben Ezra, as Kimchi observes, refers this to Hezekiah:

whose whole heart he directed, or prepared to seek the Lord, &c. by prayer and supplication for everyone of the said persons:

though he be not cleansed according to the purification of the sanctuary: according to the ceremonial law, which the service of the temple required; since, though they were attended with a ceremonial impurity, had a moral purity, and their hearts were right with God.
