Exodus 16:25-26

25Moses said, ‘Eat the food today, because this day is a Sabbath day, to worship the Lord. You will not find any food on the ground today.

26On six days of each week, you must pick food up from the ground. But on the seventh day of the week, there will not be any food on the ground. That is because the seventh day is the Sabbath day of rest.’
