Exodus 16:21-23

Living Bible

²¹ So they gathered the food morning by morning, each home according to its need; and when the sun became hot upon the ground, the food melted and disappeared. ²² On the sixth day there was twice as much as usual on the ground—four quarts instead of two; the leaders of the people came and asked Moses why this had happened.

²³ And he told them, “Because the Lord has appointed tomorrow as a day of seriousness and rest, a holy Sabbath to the Lord when we must refrain from doing our daily tasks. So cook as much as you want to today, and keep what is left for tomorrow.”
