And when the day began to wear away, then came the twelve, and said unto him, Send the multitude away, that they may go into the towns and country round about, and lodge, and get food: for we are here in a desert place.

The five loaves are understood as the five books of Moses. Rightly, they are not wheat but barley loaves because they belong to the Old Testament. You know that barley was created in such a way that one can scarcely get to its kernel. This kernel is clothed with a covering of husk, and this husk is tenacious and adhering, so that it is stripped off with effort. Such is the letter of the Old Testament, clothed with the coverings of carnal mysteries. If one gets to its kernel, it feeds and satisfies.
