Theophylact of Ohrid
Catena Aurea · Markusevangelium 6
And when the day was now far spent, his disciples came unto him, and said, This is a desert place, and now the time is far passed: Send them away, that they may go into the country round about, and into the villages, and buy themselves bread: for they have nothing to eat. He answered and said unto them, Give ye them to eat. And they say unto him, Shall we go and buy two hundred pennyworth of bread, and give them to eat? He saith unto them, How many loaves have ye? go and see. And when they knew, they say, Five, and two fishes. And he commanded them to make all sit down by companies upon the green grass. And they sat down in ranks, by hundreds, and by fifties. And when he had taken the five loaves and the two fishes, he looked up to heaven, and blessed, and brake the loaves, and gave them to his disciples to set before them; and the two fishes divided he among them all. And they did all eat, and were filled. And they took up twelve baskets full of the fragments, and of the fishes. And they that did eat of the loaves were about five thousand men.
He also looks up to heaven, that He may teach us to seek our food from God, and not from the devil, as they do who unjustly feed on other men’s labours. By this also He intimated to the crowd, that He could not be opposed to God, since He called upon God. And He gives the bread to His disciples to set before the multitude, that by handling the bread, they might see that it was an undoubted miracle. It goes on: And they did all eat, and were filled: and they took up twelve baskets full of the fragments. Twelve baskets of fragments remained over and above, that each of the Apostles, carrying a basket on his shoulder, might recognise the unspeakable wonder of the miracle. For it was a proof of overflowing power not only to feed so many men, but also to leave such a superabundance of fragments. Even though Moses gave manna, yet what was given to each was measured by his necessity, and what was over and above was overrun with worms. Elias also fed the woman, but gave her just what was enough for her; but Jesus, being the Lord, makes his gifts with superabundant profusion.
