NET Bible
"The majority of the many people from Ephraim, Manasseh, Issachar, and Zebulun were ceremonially unclean, yet they ate the Passover in violation of what is prescribed in the law. For Hezekiah prayed for them, saying:“May the LORD, who is good, forgive"
— 2 Chronicles 30:18, NET Bible
“For a multitude of the people, even many of Ephraim, and Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet did they eat the passover otherwise than it was written. But Hezekiah prayed for them, saying, The good Lord pardon every one”
“For a great number of the people from Ephraim and Manasseh, Issachar and Zebulun, had not made themselves clean, but they took the Passover meal, though not in the right way. For Hezekiah had made prayer for them, saying, May the good Lord have mercy on everyone”
They slaughtered the Passover lamb on the fourteenth day of the second month. The priests and Levites were ashamed, so they consecrated themselves and brought burnt sacrifices to the LORD’s temple.
They stood at their posts according to the regulations outlined in the law of Moses, the man of God. The priests were splashing the blood as the Levites handed it to them.
Because many in the assembly had not consecrated themselves, the Levites slaughtered the Passover lambs of all who were ceremonially unclean and could not consecrate their sacrifice to the LORD.
The majority of the many people from Ephraim, Manasseh, Issachar, and Zebulun were ceremonially unclean, yet they ate the Passover in violation of what is prescribed in the law. For Hezekiah prayed for them, saying:“May the LORD, who is good, forgive
everyone who has determined to follow God, the LORD God of his ancestors, even if he is not ceremonially clean according to the standards of the temple.”
The LORD responded favorably to Hezekiah and forgave the people.
The Israelites who were in Jerusalem observed the Feast of Unleavened Bread for seven days with great joy. The Levites and priests were praising the LORD every day with all their might.
