As a reward for Abraham's readiness, in answer to the summons to sacrifice Isaac, when he said, "Here am I," God promised manna to the descendants of Abraham with the same words, "Here I am." In the same way, during their wanderings through the wilderness, God repaid the descendants of Abraham for what their ancestor had done by the angels who visited him. He himself had fetched bread for them, and likewise God Himself caused bread to rain from heaven; he himself ran before them on their way, and likewise God moved before Israel; he had water fetched for them, and likewise God, through Moses, caused water to flow from the rock; he bade them seek shade under the tree, and likewise God had a cloud spread over Israel. [92] Then God spoke to Moses: "I will immediately reveal Myself without Jacob, 'I will rain bread from My treasure in heaven for you; and the people shall go out and gather a certain rate every day.'" There were good reasons for not exceeding a day's ration in the daily downpour of manna. First, that they might be spared the need of carrying it on their wanderings; secondly, that they might daily receive it hot; and, lastly, that they might day by day depend upon God's aid, and in this way exercise themselves in faith. [93] While the people were still abed, God fulfilled their desire, and rained down manna for them. For this food had been created on the second day of creation, [94] and ground by the angels, it later descended for the wanderers in the wilderness. [95] The mills are stationed in the third heaven, where manna is constantly being ground for the future use of the pious; [96] for in the future world manna will be set before them. [97] Manna deserves its name, "bread of the angels," not only because it is prepared by them, but because those who partake of it become equal to the angels in strength, and, furthermore, like them, have no need of easing themselves, as manna is entirely dissolved in the body. Not until they sinned, did they have to ease themselves like ordinary mortals. [98] Manna also showed its heavenly origin in the miraculous flavor it possessed. There was no need of cooking or baking it, nor did it require any other preparation, and still it contained the flavor of every conceivable dish. One had only to desire a certain dish, and no sooner had he thought of it, than manna had the flavor of the dish desire. The same food had a different taste to every one who partook of it, according to his age; to the little children it tasted like milk, to the strong youths like bread, to the old men like honey, to the sick like barley steeped in oil and honey.
