Exodus 16:26-36

You may gather the food for six days, but the seventh day is the Sabbath. There will be no food on the ground that day.” Some of the people went out anyway on the seventh day, but they found no food. The LORD asked Moses, “How long will these people refuse to obey my commands and instructions? They must realize that the Sabbath is the LORD’s gift to you. That is why he gives you a two-day supply on the sixth day, so there will be enough for two days. On the Sabbath day you must each stay in your place. Do not go out to pick up food on the seventh day.” So the people did not gather any food on the seventh day. The Israelites called the food manna. It was white like coriander seed, and it tasted like honey wafers. Then Moses said, “This is what the LORD has commanded: Fill a two-quart container with manna to preserve it for your descendants. Then later generations will be able to see the food I gave you in the wilderness when I set you free from Egypt.” Moses said to Aaron, “Get a jar and fill it with two quarts of manna. Then put it in a sacred place before the LORD to preserve it for all future generations.” Aaron did just as the LORD had commanded Moses. He eventually placed it in the Ark of the Covenant—in front of the stone tablets inscribed with the terms of the covenant. So the people of Israel ate manna for forty years until they arrived at the land where they would settle. They ate manna until they came to the border of the land of Canaan. The container used to measure the manna was an omer, which was one-tenth of an ephah; it held about two quarts.
