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.
Arcana Coelestia #221
221. 'Breeze, or breath, 1 of the daytime' means a time when the Church still had a residue of perception. This becomes clear from the meaning of 'day' and of 'night'. The most ancient people compared states of the Church to the times of the day and of the night. States when the Church still had light they compared to times of the day; therefore this verse speaks of 'the breath' or breeze of the daytime' as when they still had some residue of perception, from which they knew that they were fallen. The Lord too calls a state in which there is faith 'the daytime' and one in which there is none 'the night', as in John,
I must work the works of Him who sent Me while it is day; night is coming when nobody will be able to work. John 9:4.
The consecutive states of man's regeneration for the same reason were called 'days' in Chapter Genesis 1.
