In the pastures of grass, they will lie me down beside still waters. Rabbi Elazar asked Rabbi Shimon and said to him, "When the Israelites left Egypt, did they take with them linen garments?" He said to him, "Yes." "And from where did they get clothing to wear for forty years?"
He said to them, "The ministering angels clothed them, as it says, 'I clothed you with embroidered work' (Ezekiel 16:10)." "And what is 'embroidered work'?" Rabbi Simai said, "It means 'fine wool.'" He said to him, "But they did not wear out."
"And what about the fact that their clothes did not become dirty?" He said to him, "The cloud laundered them and pressed them." "And what about the fact that they did not smell bad from sweat since they did not change their clothes?" He said to him, "The well would bring up all kinds of fragrant herbs, and they would long for them, as it says, 'In the pastures of grass, they will lie me down beside still waters' (Psalms 23:2)."
When the Israelites saw how God was treating them with care and luxury in the wilderness, they began to praise and say, "He feeds us good food, and we lack nothing. The Lord is my shepherd, I shall not want. In the pastures of grass, He will lie me down beside still waters." Rabbi Samuel said, "There are waters that are suitable for drinking but not for washing, and there are waters that are suitable for washing but not for drinking. But the water of the well was suitable for both."
