Envy. We call it the “green-eyed monster.” That phrase probably started with Shakespeare when he wrote the tragedy Othello in 1603, “O, beware, my lord, of jealousy; it is the green-eyed monster which doth mock.”
Long before Shakespeare or even Pope Gregory put their fingers on envy as a deadly sin and a vicious vice, Moses descended the slope of Mount Sinai with two clay tablets, each written upon by the finger of Almighty God. We know them as the Ten Commandments. The tenth one places a bullseye on the green-eyed monster.
“You shall not covet your neighbor's house; you shall not covet your neighbor's wife, or his male servant, or his female servant, or his ox, or his donkey, or anything that is your neighbor's” (Exodus 20:17).
