'Purge' in the Bible

For in the eighth year of his reign, while he was yet young, he began to seek after the God of David his father; and in the twelfth year he began to purge Judah and Jerusalem from the high places, and the Asherim, and the graven images, and the molten images.

and I will turn my hand upon thee, and thoroughly purge away thy dross, and will take away all thy tin;

and I will purge out from among you the rebels, and them that transgress against me; I will bring them forth out of the land where they sojourn, but they shall not enter into the land of Israel: and ye shall know that I am Jehovah.
