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 slaughter the passover lamb for everyone who was not clean, to make it holy to the Lord.
18 For a multitude of the people, many of them from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the passover otherwise than as prescribed. But Hezekiah prayed for them, saying, "The good Lord pardon all
19 who set their hearts to seek God, the Lord the God of their ancestors, even though not in accordance with the sanctuary's rules of cleanness."
20 The Lord heard Hezekiah, and healed the people.
21 The people of Israel who were present at Jerusalem kept the festival of unleavened bread seven days with great gladness; and the Levites and the priests praised the Lord day by day, accompanied by loud instruments for the Lord.
