Seven Sins That Bring the Plagues of Leprosy

"And the LORD plagued Pharaoh" (Genesis 12:17). Rabbi Samuel bar Nachmani said in the name of Rabbi Jonathan: for seven things plagues of leprosy come. For evil speech, as it is written, "Whoever slanders his neighbor in secret, him will I destroy" (Psalms 101:5). For bloodshed, as it is written, "Let there not fail from the house of Joab one who has an issue or who is leprous" (2 Samuel 3:29). For a false oath, as it is written, "Be content, take the talents" (2 Kings 5:23) and "oath" means nothing other than a sworn statement, as it says, "And if a soul sin, and hear the voice of adjuration" (Leviticus 5:1) and it is written, "The leprosy therefore of Naaman shall cleave to you" (2 Kings 5:27). For uncovering nakedness [forbidden relations], as it is written, "And the LORD plagued Pharaoh." For arrogance of spirit, as it is written, "But when he was strong, his heart was lifted up" (2 Chronicles 26:16) and it is written, "And the leprosy broke out on his forehead" (concerning Uzziah). For robbery, as it is written, "Then the priest shall command that they empty the house" (Leviticus 14:36) it was taught: he gathered money that was not his; let the priest come and scatter his money. For a grudging eye, as it is written, "And he that owns the house shall come" (Leviticus 14:35) and the school of Rabbi Ishmael taught: one who keeps his house to himself alone.
