Wheat
As the finest of the grains, wheat fittingly represents the finest of spiritual food, what Swedenborg calls "the good of love and charity" – which is the desire for good that springs from love of the Lord and love of serving others.
From a nutritional standpoint, wheat is packed with complex carbohydrates, a good source of lasting energy – and the desire for good from love of the Lord and love of the neighbor is a good source of lasting spiritual energy. Yet the carbohydrate-rich heart of each grain of wheat is covered by a hull rich with vitamins, protein and fiber, building blocks for the body – much as the desire for good is clothed in ideas of how to put good into action.

Jeremiah 12:12-13
12
Destroyers are come on all the bare heights in the wilderness; for the sword of Yahweh devours from the one end of the land even to the other end of the land: no flesh has peace.
13
They have sown wheat, and have reaped thorns; they have put themselves to pain, and profit nothing: and you shall be ashamed of your fruits, because of the fierce anger of Yahweh.
