Context

“necessary are the envy and the distrust and the back-biting among the virtues. Lo! how each of thy virtues is covetous of the highest place; it wanteth thy whole spirit to be ITS herald, it wanteth thy whole power, in wrath, hatred, and love. Jealous is every virtue of the others, and a dreadful thing is jealousy. Even virtues may succumb by jealousy. He whom the flame of jealousy encompasseth, turneth at last, like the scorpion, the poisoned sting against himself. Ah! my brother, hast thou never seen a virtue backbite and stab itself?” source
