2 Chronicles 30:19

19 Although many people from Ephraim, Manasseh, Issachar, and Zebulun had not purified themselves for the feast, they ate the Passover even though it was against the law. So Hezekiah prayed for them, saying, "Lord, you are good. You are the Lord, the God of our ancestors. Please forgive all those who try to obey you even if they did not make themselves clean as the rules of the Temple command."

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.

19 Although many people from Ephraim, Manasseh, Issachar, and Zebulun had not purified themselves for the feast, they ate the Passover even though it was against the law. So Hezekiah prayed for them, saying, "Lord, you are good. You are the Lord, the God of our ancestors. Please forgive all those who try to obey you even if they did not make themselves clean as the rules of the Temple command."

20 The Lord listened to Hezekiah's prayer, and he healed the people.
