Ecclesiastes Rabbah 5:13

¹“That wealth is lost in a grievous manner; he begets a son, and he has nothing in his hand” (Ecclesiastes 5:13). “That wealth is lost in a grievous manner” – Rabbi Ḥaggai said in the name of Rabbi Yitzḥak: [His wealth is lost] due to the grievous manner in which he thought about a certain pauper. He said to him: ‘Would it not be better for you to toil and eat? Look at your thighs, look at your feet, look at your girth; would it not be better for you to toil and eat?’ The Holy One blessed be He said: Is it not enough that you did not give him anything of what is yours, that you cast an evil eye on what I gave him? Therefore, “he begets a son, and he has nothing in his hand” – he will not leave, from the money in his possession, for his son.
