Kabbalah do Wyjścia 16:18

Rebbe Yitzchak said, "they had gathered as much as they needed to eat" (Shmot 16:18). For the one who eats less, gathered less, and the one who eats more, gathered more. Yet it is written, "the one who had gathered much had no excess, and the one who had gathered little had no deficiency." Rather, according to what they ate, they gathered. It says, "their eating", that which they would actually eat, which is why it doesn't say, "their food".
