Matthew 14:21

The same number of those eating proved to be the number of those who believed. As noted in the book of Acts, out of the countless people of Israel five thousand men believed. Once the people had been satisfied, when they took up the loaves that had been broken into pieces with the fish, there was enough left over to match the number of believers and apostles to be filled with heavenly grace. Thus both the measure suited the number and the number the measure. Within its bounds the calculation was keyed to the proper effect and depended on the guidance of divine power.

Then the loaves are given to the Apostles, because through them the gifts of divine grace were to be rendered. And the number of them that did eat is found to be the same as that of those who should believe; for we find in the book of Acts that out of the vast number of the people of Israel, five thousand men believed.

But He is about to feed them also. And He doth not this of Himself, but waits to be entreated; on every occasion, as I have said, maintaining this rule, not to spring onward to His miracles, preventing them, but upon some call. And why did none of the multitude come near and speak for them? They reverenced Him exceedingly, and felt not even their hunger, through their longing to stay with Him. Neither indeed do His disciples, when they were come to Him, say, "Feed them;" for as yet they were rather in an imperfect state; but what? "And when it was evening," it is said, "His disciples came to Him, saying, This is a desert place, and the time is now passed; send the multitude away, that they may go and buy themselves victuals." For if even after the miracle they forgot what had been done, and after the baskets, supposed Him to be speaking of loaves, when He gave the name of "leaven" to the doctrine of the Pharisees; much less, when they had never yet had experience of such a miracle, would they have expected any such thing. And yet He had made a beginning by actually healing many sick; but nevertheless, not even from this did they expect the miracle of the loaves; so imperfect were they as yet. But mark thou, I pray, the Teacher's skill, how distinctly He summons them on towards believing. For He said not at once, "I feed them;" which indeed would not have been easily received; but what? "But Jesus," so it is written, "said unto them, They need not depart; give ye them to eat." He said not, "I give them," but, "Give ye them;" for as yet their regard to Him was as to a man. […]

(Verse 21) Now the number of those who ate was five thousand men, besides women and children. According to the number of five loaves and the multitude of five thousand men who ate, it had not yet reached the seven-fold number according to another account, of whom there are four thousand who eat, close to the number of the Gospels. But those who ate were five thousand men who had grown into full maturity, and they followed him of whom Zacharias says: Behold the man, his name is the Rising Sun. But women and children, being of the weaker sex and younger age, are considered unworthy of being counted. Therefore, in the Book of Numbers, whenever priests, Levites, armies, or fighting crowds are described, slaves, women, children, and the common people are omitted from the count.

Then the number of those who ate is presented: and the number of those who ate was five thousand men, so that one thousand ate from each loaf, according to Hilary. This also happened after the Ascension, when at the voice of the apostles five …
