Exodus 16:23-24, 28-29

Moses said, “This is what GOD was talking about: Tomorrow is a day of rest, a holy Sabbath to GOD. Whatever you plan to bake, bake today; and whatever you plan to boil, boil today. Then set aside the leftovers until morning.” They set aside what was left until morning, as Moses had commanded. It didn’t smell bad and there were no worms in it.

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.”
