Theophylact of Ohrid
Catena Aurea · Lukasevangelium 9
And the apostles, when they were returned, told him all that they had done. And he took them, and went aside privately into a desert place belonging to the city called Bethsaida. And the people, when they knew it, followed him: and he received them, and spake unto them of the kingdom of God, and healed them that had need of healing. And when the day began to wear away, then came the twelve, and said unto him, Send the multitude away, that they may go into the towns and country round about, and lodge, and get victuals: for we are here in a desert place. But he said unto them, Give ye them to eat. And they said, We have no more but five loaves and two fishes; except we should go and buy meat for all this people. For they were about five thousand men. And he said to his disciples, Make them sit down by fifties in a company. And they did so, and made them all sit down. Then he took the five loaves and the two fishes, and looking up to heaven, he blessed them, and brake, and gave to the disciples to set before the multitude. And they did eat, and were all filled: and there was taken up of fragments that remained to them twelve baskets.
Now He said not this as ignorant of their answer, but wishing to induce them to tell Him how much bread they had, that so a great miracle might be manifested through their confession, when the quantity of bread was made known.
