'Unclean' in the Bible

Jesus called his twelve disciples and gave them authority over unclean spirits so they could cast them out and heal every kind of disease and sickness.

"When an unclean spirit goes out of a person, it passes through waterless places looking for rest but does not find it.

"Woe to you, experts in the law and you Pharisees, hypocrites! You are like whitewashed tombs that look beautiful on the outside but inside are full of the bones of the dead and of everything unclean.
