YLT(i)
17 for many are in the assembly who have not sanctified themselves, and the Levites are over the slaughtering of the passover-offerings for every one not clean, to sanctify him to Jehovah:
18 for a multitude of the people, many from Ephraim and Manasseh, Issachar, and Zebulun, have not been cleansed, but have eaten the passover otherwise than it is written; but Hezekiah prayed for them, saying, `Jehovah, who is good, doth receive atonement for every one
19 who hath prepared his heart to seek God—Jehovah, God of his fathers—yet not according to the cleansing of the sanctuary;'
20 and Jehovah hearkeneth unto Hezekiah, and healeth the people.
