Exodus 16
22 Ref It happened that on the sixth day they gathered twice as much bread, two omers for each one, and all the rulers of the congregation came and told Moses.
23 Ref He said to them, "This is that which Yahweh has spoken, 'Tomorrow is a solemn rest, a holy Sabbath to Yahweh. Bake that which you want to bake, and boil that which you want to boil; and all that remains over lay up for yourselves to be kept until the morning."
24 Ref They laid it up until the morning, as Moses asked, and it didn't become foul, neither was there any worm in it.
25 Ref Moses said, "Eat that today, for today is a Sabbath to Yahweh. Today you shall not find it in the field.
26 Ref Six days you shall gather it, but on the seventh day is the Sabbath. In it there shall be none."
27 Ref It happened on the seventh day, that some of the people went out to gather, and they found none.
28 Ref Yahweh said to Moses, "How long do you refuse to keep my commandments and my laws?
29 Ref Behold, because Yahweh has given you the Sabbath, therefore he gives you on the sixth day the bread of two days. Everyone stay in his place. Let no one go out of his place on the seventh day."
