God has created man. The first two people heard God’s command for mankind. They require food to live. The Lord determines man’s menu. These are the fruits that hang from the trees and the plants that give seed. We can think of the latter as grains, among other things.
29 And God said, “Behold, I have given you every plant yielding seed that is on the face of all the earth, and every tree with seed in its fruit. You shall have them for food.
