Matthew 15:37

They brought forward seven loaves of bread. The Gentiles received no salvation from the law and the prophets. However, they live because of the grace of the Spirit whose sevenfold light, as noted by Isaiah, is a gift. Therefore through faith in the Spirit the Gentiles receive salvation. They recline on the ground, for they were not subject to any works of the law or the flesh but were called in their earthly condition to the Spirit of the sevenfold light. The indefinite number of fish signifies the variety and dispensing of gifts and charisma, by which a diversity of graces satisfied the faith of the Gentiles. Moreover, the fact that seven baskets are filled indicates the overflowing and multiplied abundance of the Spirit of sevenfold light. What he generously gives, abounds. Having been satisfied, the gift becomes ever more richly endowed and full. The fact that four thousand men gather together refers to a multitude of countless people from the four corners of the earth. In terms of the future, a calculated number of people are satisfied in as many thousands of places as there are thousands of believers who hasten to receive the gift of heavenly food. Having been fully fed, the crowd is dismissed. And since the Lord remains with us all the days of our life, a great number of Gentile believers go on board the ship—namely, the church.

But when we come to the end, there is a difference. For, "they did all eat," so it is said, "and were filled, and they took up of the broken meat that was left, seven baskets full. And they that did eat were four thousand men, besides women and children." But why at the former time, when there were five thousand, did twelve baskets full remain over and above, whereas here, when there were four thousand, it was seven baskets full? For what purpose, I say, and by what cause, were the remnants less, the guests not being so many? Either then one may say this, that the baskets on this last occasion were greater than those used before, or if this were not so, lest the equality of the miracle should again cast them into forgetfulness, He rouses their recollection by the difference, that by the variation they might be reminded of both one and the other. Accordingly, in that case, He makes the baskets full of fragments equal in number to His disciples, in this, the other baskets equal to the loaves; indicating even hereby His unspeakable power, and the ease wherewith He exercised His authority, in that it was possible for Him to work such miracles, both in this way and in the other. For neither was it of small power, to maintain the exact number, both then and now; then when there were five thousand, now when there were four thousand; and not suffer the remnants to be more than the baskets used on the one occasion or on the other, although the number of the guests was different.
