Exodus 16:27-30

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.
