Then the LORD said to Moses, “Behold, I will rain down bread from heaven for you. Each day the people are to go out and gather enough for that day. In this way I will test whether or not they will follow My instructions.” … When the layer of dew had evaporated, there were thin flakes on the desert floor, as fine as frost on the ground. When the Israelites saw it, they asked one another, ”What is it?” For they did not know what it was. So Moses told them, ”It is the bread that the LORD has given you to eat.”
Exodus 16:4, 14-15 (BSB)
