Kabbalah su Genesi 21:8

Whom do we have in the world greater than Abraham, who had bestowed kindness on all living beings? Of the day that he prepared a feast, what is written? "And the child grew, and was weaned. And Abraham made a great feast on the day that Issac was weaned" (Gen. 21:8). So Abraham prepared a feast and invited all the leaders and important people of that generation to that feast. And we have learned that at every banquet, the 'Accuser' wanders about, observing if each person first dispenses charity to the poor. If there are any poor people in his house, then he (the "Accuser") leaves that house and does not enter. But if not, the Accuser enters that house. If he sees the merrymaking without the poor and without having first dispensed charity to the poor, he ascends above and brings accusations against him.
