Attribute not the good actions of another to bad causes: thou canst not know his heart; but the world will know by this that thine is full of envy.
Few men have the natural strength to honour a friend’s success without envy.
Envy is like a fly that passes all a body’s sounder parts, and dwells upon the sores.
~ George Chapman
An envious man waxeth lean with the fatness of his neighbors. Envy is the daughter of pride, the author of murder and revenge, the beginner of secret sedition, and the perpetual tormenter of virtue. Envy is the filthy slime of the soul; a venom, a poison, or quicksilver which consumeth the flesh, and drieth up the marrow of the bones.
Bad neighbors count a man’s income, but not his expenses.
~ Talmud, Pesikta Rabbati, Pes., 31; Tanhuma Buber, Wayyikra, 6
