'Cleansed' in the Bible

Then they went in to Hezekiah the king within the palace , and said, We have cleansed all the house of Jehovah, and the altar of burnt-offering, with all the vessels thereof, and the table of showbread, with all the vessels thereof.

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 is written. For Hezekiah had prayed for them, saying, The good Jehovah pardon every one

that setteth his heart to seek God, Jehovah, the God of his fathers, though he be not cleansed according to the purification of the sanctuary.
