'Purify' in the Bible

Then he said to them, “Levites, listen to me! Now consecrate (dedicate) yourselves and consecrate the house of the Lord, the God of your fathers, and get the filth [of idol worship] out of the Holy Place.

They assembled their brothers and consecrated themselves. Then they went in to purify the Lord's temple, just as the king had ordered, in accordance with the word of the Lord.

The priests then entered the Lord's temple to purify it; they brought out to the courtyard of the Lord's temple every ceremonially unclean thing they discovered inside. The Levites took them out to the Kidron Valley.

And in the eighteenth year of his reign, to purify the land and the house he hath sent Shaphan son of Azaliah, and Maaseiah head of the city, and Joah son of Johaz the remembrancer, to strengthen the house of Jehovah his God.
