It is not without a reason that the Evangelist says, “After the manner of the purifying of the Jews,” but in order that none of the unbelievers might suspect that lees having been left in the vessels, and water having been poured upon and mixed with them, a very weak wine had been made. Therefore he says, “after the manner of the purifying of the Jews,” to show that those vessels were never receptacles for wine. For because Palestine is a country with but little water, and brooks and fountains were not everywhere to be found, they always used to fill waterpots with water, so that they might not have to hasten to the rivers if at any time they were defiled, but might have the means of purification at hand.
