Jealousy, the green-eyed elf

Beware of jealousy, the green-eyed elf,
That makes the food on which it feeds itself;
And scorn hypocrisy, the infernal bane,
That prays like Abel and performs like Cain.

from “Address by E. R. Snow Smith” (1844), in Eliza R. Snow: The Complete Poetry, Brigham Young University Press, p. 1012
