Kabbalah su Genesi 21:7

When Abraham summoned all the great leaders of that generation, the 'Accuser' descended and stood at the door disguised as a poor man. And nobody paid any attention to him. Abraham was attending the kings and the noble men. Sarah suckled all their children because they did not believe that she had born a child, but rather claimed that he was a foundling whom they picked up from the marketplace. This is why they brought their children with them, so that Sarah could take them and nurse them in front of their parents. As it is written: 1. "Who would have said to Abraham that Sarah would nurse children?" (Gen. 21:7). (The verse should have said 'would nurse a child) There is no doubt that it should be 'children,'. And that 'Accuser' was at the door. Sarah said: "Elohim made laughter for me!"(Ibid. 6). 2. So immediately the 'Accuser' went up and stood before the Holy One, blessed be He, and said to Him, "O Master of the universe, You have said, 'Abraham is the one who loves Me,' and here he prepared a feast but did not give anything to You or to the poor. He did not sacrifice even one pigeon before. And furthermore, Sarah claims that You have mocked her!"
