Note 6 at Joh 2:6: Scholars refer to a firkin as being equal to about 9 gallons. That would mean these six water pots full of water turned into between 108 to 162 gallons of wine. This illustrates God's idea of abundance, as does the twelve baskets of fragments left over from feeding the 5,000 men (Mt 14:15-21, Mr 6:33-44, Lu 9:11-17, and Joh 6:5-14) and the seven baskets of food remaining after the feeding of the 4,000 men (Mt 15:32-38 and Mr 8:1-9). Compare with 2Co 9:8-11.
