'Cleanse' in the Bible

They gathered their brothers (fellow Levites) together, consecrated themselves, and went in to cleanse the house of the Lord, as the king had commanded by the words of the Lord.

The priests went into the inner part of the house of the Lord to cleanse it, and every unclean thing they found in the temple of the Lord they brought out to the courtyard of the Lord’s house. Then the Levites received it to take out to the Kidron Valley [for disposal].
