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 the charge of killing the Pesachim for everyone who was not clean, to sanctify them to the LORD.

18 For a multitude of the people, even many of Efrayim and Menashsheh, Yissakhar and Zevulun, had not cleansed themselves, yet did they eat the Pesach otherwise than it is written. For Hizkiyahu had prayed for them, saying, The good the LORD pardon everyone

19 who sets his heart to seek God, the LORD, the God of his fathers, though not [cleansed] according to the purification of the sanctuary.

20 The LORD listened to Hizkiyahu, and healed the people.

21 The children of Yisra'el who were present at Yerushalayim kept the feast of matzah seven days with great gladness; and the Levites and the Kohanim praised the LORD day by day, [singing] with loud instruments to the LORD.
