Exodus 16:23, Exodus 16:25-26, Exodus 16:29-30

²³And he said to them, “This is what Yahweh has spoken: ^aTomorrow is a sabbath observance, a holy sabbath to Yahweh. Bake what you will bake and boil what you will boil, and ^ball that is in excess ¹put aside to be kept until morning.”

²⁵And Moses said, “Eat it today, for today is a sabbath to Yahweh; today you will not find it in the field. ²⁶“^aSix days you shall gather it, but on the seventh day, the sabbath, there will be ¹none.”

²⁹“See, Yahweh has given you the sabbath; therefore He gives you bread for two days on the sixth day. Remain every man in his place; let no man go out of his place on the seventh day.” ³⁰So the people rested on the seventh day.
