'Cleansed' in the Bible

Then they went in to Hezekiah the king, and said, We have cleansed all the house of the LORD, and the altar of burnt offering, with all the vessels thereof, and the shewbread table, 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 was written. But Hezekiah prayed for them, saying, The good LORD pardon every one

That prepareth his heart to seek God, the LORD God of his fathers, though he be not cleansed according to the purification of the sanctuary.

And he burnt the bones of the priests upon their altars, and cleansed Judah and Jerusalem.
