Exodus 16:25-30

Moses said, “Now eat it; this is the day, a Sabbath for GOD. You won’t find any of it on the ground today. Gather it every day for six days, but the seventh day is Sabbath; there won’t be any of it on the ground.” On the seventh day, some of the people went out to gather anyway but they didn’t find anything. GOD said to Moses, “How long are you going to disobey my commands and not follow my instructions? Don’t you see that GOD has given you the Sabbath? So on the sixth day he gives you bread for two days. So, each of you, stay home. Don’t leave home on the seventh day.” So the people quit working on the seventh day.
