God provided their daily necessities, food in particular. In our day we would say manna everyday did not have enough nutrition, we would not call it balanced diet food, it was all carbohydrates.

God is the giver and the sustainer of life, He should be remembered, acknowledged and thanked for who He is and what He has done.
