The Bible
Exodus 16
Israel murmurs for want of bread and lusts for the fleshpots of Egypt—The Lord rains bread from heaven and sends quail for meat—Israel is given manna each day, except the Sabbath, for forty years.
11¶ And the Lord spake unto Moses, saying,

17And the children of Israel did so, and gathered, some more, some less.
19And Moses said, Let no man leave of it till the morning.
28And the Lord said unto Moses, How long refuse ye to keep my commandments and my laws?
30So the people rested on the seventh day.
34As the Lord commanded Moses, so Aaron laid it up before the Testimony, to be kept.
