John 2:6

6. Six waterpots of stone Used for the washings and purifications described in Mark 7:3, etc. The firkin is equal probably to the Jewish bath, which contained 8 gallons, 7.4 pints. According to this, the quantity of wine thus created would be two or three times 8 gallons 7.4 pints, multiplied by 6. This would be between 17 and 25 gallons, multiplied by 6. Taking the medium between 17 and 25, say 21 gallons, multiply by 6, and we have 126 gallons. So great, similarly, was the miraculous draught of fishes as almost to submerge two fishermen’s boats. Twelve baskets full remain at the end of the meal, where there were but seven loaves at the beginning. The wine, the very fresh blood, shed through the vine, from the rich heart of nature the ruddy image of the saving blood of nature’s Lord is here poured forth with a profusion that richly symbolizes the freeness and intrinsic boundlessness of his salvation. And no doubt Jesus, like the God of nature, created not the alcohol, which is the poison produced by the putrefying corpse of the dead grape, but the fresh, living, innocent fluid. The fact of their being waterpots was proof against any charge of fraud.
