2 Chronicles 30:19 Meaning and Commentary

2 Chronicles 30:19

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
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.

2 Chronicles 30:19 In-Context

17 For there were many in the assembly who had not sanctified themselves; therefore the Levites had to kill the passover lamb for every one who was not clean, to make it holy to the LORD.

18 For a multitude of the people, many of them from E'phraim, Manas'seh, Is'sachar, and Zeb'ulun, had not cleansed themselves, yet they ate the passover otherwise than as prescribed. For Hezeki'ah had prayed for them, saying, "The good LORD pardon every one

19 who sets his heart to seek God, the LORD the God of his fathers, even though not according to the sanctuary's rules of cleanness."

20 And the LORD heard Hezeki'ah, and healed the people.

21 And the people of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised the LORD day by day, singing with all their might to the LORD.
