For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it.

Exodus 16:22-30 And so it was, on the sixth day, that they gathered twice as much bread, two omers for each one. And all the rulers of the congregation came and told Moses. Then he said to them, "This is what the LORD has said: "Tomorrow is a Sabbath rest, a holy Sabbath to the LORD. Bake what you will bake today, and boil what you will boil; and lay up for yourselves all that remains, to be kept until morning."" So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it. Then Moses said, “Eat that today, for today is a Sabbath to the LORD; today you will not find it in the field. Six days you shall gather it, but on the seventh day, the Sabbath, there will be none.” Now it happened that some of the people went out on the seventh day to gather, but they found none. And the LORD said to Moses, “How long do you refuse to keep My commandments and My laws? See! For the LORD has given you the Sabbath; therefore He gives you on the sixth day bread for two days. Let every man remain in his place; let no man go out of his place on the seventh day.” So the people rested on the seventh day.
