When this spell is cast, the cleric causes food and/or water to appear. The food thus created is highly nourishing, and each cubic foot of the material will sustain three human-sized creatures or one horse-sized creature for a full day. For each level of experience the cleric has attained, 1 cubic foot of food and/or water is created by the spell, ie. 2 cubic feet of food are created by a 2nd level cleric, 3 by a 3rd, 4 by a 4th, and so on; or the 2nd level cleric could create 1 cubic foot of food and 1 cubic foot of water, etc.
