'Cleanse' in the Bible

and the priests and the Levites are cleansed, and they cleanse the people, and the gates, and the wall.

and I speak, and they cleanse the chambers, and I bring back thither the vessels of the house of God with the present and the frankincense.

And I commanded the Levites that they should cleanse themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember me, O my God, concerning this also, and spare me according to the greatness of thy mercy.
