Exodus 16:26-36
16:26 Six days you will gather it, but on the seventh day, the Sabbath, there will not be any.”
16:27 On the seventh day some of the people went out to gather it, but they found nothing.
16:28 So the Lord said to Moses, “How long do you refuse to obey my commandments and my instructions?
16:29 See, because the Lord has given you the Sabbath, that is why he is giving you food for two days on the sixth day. Each of you stay where you are; let no one go out of his place on the seventh day.”
16:30 So the people rested on the seventh day.
16:31 The house of Israel called its name “manna.” It was like coriander seed and was white, and it tasted like wafers with honey.
16:32 Moses said, “This is what the Lord has commanded: ‘Fill an omer with it to be kept for generations to come, so that they may see the food I fed you in the desert when I brought you out from the land of Egypt.’”
16:33 Moses said to Aaron, “Take a jar and put in it an omer full of manna, and place it before the Lord to be kept for generations to come.”
16:34 Just as the Lord commanded Moses, so Aaron placed it before the Testimony for safekeeping.
16:35 Now the Israelites ate manna forty years, until they came to a land that was inhabited; they ate manna until they came to the border of the land of Canaan.
16:36 (Now an omer is one tenth of an ephah.)
