Midrash Leviticus Rabbah 34:4

ײַA rich man and a poor man meet. The poor man asks the rich man for charity. If the rich man says to the poor man, "Why do you not go and work and get food? Look at those hips! Look at those legs! Look at that fat body! Look at those lumps of flesh!" The Holy One, Blessed be God, says to the rich person, "It is not enough that you have not given him anything of yours and helped him out, that you must also set an evil eye upon (make fun of/mock) what I have given him?"
