'Cleanse' in the Bible

And he shall take two birds and {cedar wood} and a {crimson thread} and hyssop to cleanse the house;

And he shall spatter {some of} the blood on it seven times with his finger, and he shall cleanse it and consecrate it from the {Israelites}' impurities.

because on this day he shall make atonement for you to cleanse you; you must be clean from all your sins {before} Yahweh.
