God said to Moses: ‘At twilight you will eat meat, and in the morning you will be filled with bread. Then you will know that I am the LORD your God.’--That evening quail came and covered the camp, and in the morning there was a layer of dew around the camp. ¹⁴ When the dew was gone, thin flakes like frost on the ground appeared on the desert floor.
However, some of them paid no attention to Moses; they kept part of it until morning, but it was full of maggots and began to smell. So Moses was angry with them.
Then the LORD said to Moses, “How long will you refuse to keep my commands and my instructions? ²⁹ Bear in mind that the LORD has given you the Sabbath; that is why on the sixth day he gives you bread for two days. Everyone is to stay where they are on the seventh day; no one is to go out.”
What it is? The people of Israel called the bread manna. The Israelites ate manna forty years, until they came to a land that was settled; they ate manna until they reached the border of Canaan.
