Kabbalah su Proverbi 13:25

Rebbe Shimon said, "Come and see! The Holy One of Blessing didn't give Torah to Yisrael until the faithful could be distinguished from those without faith, who didn't desire Torah. And how were they distinguished? Through the mannah! As it says, (Shmot 16:4), "that I may thus test them [to see whether they will follow My instructions or not"]. All those found to be faithful, the Holy One of Blessing marks them, with the mark of the crown of Hesed, as it says (Tehillim 147:11), "those who rely on ha-Shem's Hesed." It is because of this that "I may test them." All those not found to be faithful, this supernal crown will be removed from them. For I proclaimed the mannah, saying (Mishlei 13:25), "[The righteous man eats to his heart’s content,] but the belly of the wicked is empty." With all this, (Shmot 16:18) "the one who had gathered much had no excess, and the one who had gathered little had no deficiency; [they had gathered as much as they needed to eat.]"
