Fruit
We tend to think of "fruit" in two ways in natural language. One is as food that grows on trees and vines, sweet and delicious, and able to be eaten without harming the plant in any way. Another is as the things we produce, what our work yields for the betterment of the world. These are obviously connected: we are like trees, producing things that "feed" the world in some way, just as the tree produces fruit that feeds us. It makes sense, then, that the idea of fruit in the Bible is bound closely to the idea of goodness. Fruits that are eaten represent the desire for good and the energy to do what is good; fruit that is produced is the actual good that we go into the world and do.
Exodus 9:22-25
22
Yahweh said to Moses, "Stretch forth your hand toward the sky, that there may be hail in all the land of Egypt, on man, and on animal, and on every herb of the field, throughout the land of Egypt."
23
Moses stretched forth his rod toward the heavens, and Yahweh sent thunder, hail, and lightning flashed down to the earth. Yahweh rained hail on the land of Egypt.
24
So there was very severe hail, and lightning mixed with the hail, such as had not been in all the land of Egypt since it became a nation.
25
The hail struck throughout all the land of Egypt all that was in the field, both man and animal; and the hail struck every herb of the field, and broke every tree of the field.
