John 2:1

We have here the story of Christ's miraculous conversion of water into wine at a marriage in Cana of Galilee. There were some few so well disposed as to believe in Christ, and to follow him, when he did no miracle; yet it was not likely that many should be wrought upon till he had something wherewith to answer those that asked, What sign showest thou? He could have wrought miracles before, could have made them the common actions of his life and the common entertainments of his friends; but, miracles being designed for the sacred and solemn seals of his doctrine, he began not to work any till he began to preach his doctrine. Now observe, I. The occasion of this miracle. Maimonides observes it to be to the honour of Moses that all the signs he did in the wilderness he did upon necessity; we needed food, he brought us manna, and so did Christ. Observe, 1. The time: the third day after he came into Galilee. The evangelist keeps a journal of occurrences, for no day passed without something extraordinary done or said. Our Master filled up his time better than his servants do, and never lay down at night complaining, as the Roman emperor did, that he had lost a day. 2. The place: it was at Cana in Galilee, in the tribe of Asher (Jos 19:28), of which, before, it was said that he shall yield royal dainties, Gen 49:20.
