'Clean' in the Bible

Everything is clean to those who are clean, but nothing is clean to those who are corrupt and unbelieving. Indeed, their very way of thinking and their consciences have been corrupted.

To be wise in mind, clean in heart, kind; working in their houses, living under the authority of their husbands; so that no evil may be said of the word of God.

Who gave himself for us, so that he might make us free from all wrongdoing, and make for himself a people clean in heart and on fire with good works.
