'Soiled' in the Bible

Uncleanness has soiled her skirts, and she gave no thought to what would follow. She fell in such a startling way, with no one to comfort her. Look, LORD, upon my affliction, because my enemy is boasting.

Come close to God [with a contrite heart] and He will come close to you. Wash your hands, you sinners; and purify your [unfaithful] hearts, you double-minded [people].

But you have a few people in Sardis who have not soiled their clothes. They will walk with me in white clothes because they are worthy.
