The one who repays good with evil,
evil will not depart from his house. Bible

“evil will not depart.” Although this could be a general principle, that a person who repays evil for good will have problems, it could also be a reference to the fact that doing evil invites “Evil,” that is, evil demons, into one’s house, i.e., into one’s life. [For more on Evil being an actual demon, see commentary on Prov. 13:21, “Evil eagerly pursues”].
