When they that fed them saw what was done, they fled, and went and told it in the city and in the country.
All Commentaries on Luke 8:34 Go To Luke 8
Theophylact of Ochrid
AD 1107
When those who had been feeding the swine fled into the city, it became an opportunity for salvation for the Gadarenes, but they did not understand. They ought to have marvelled at the Saviour's power and believed in Him. The Evangelist says that they besought Him to depart from them, instead of calling upon Him in supplication. They did this out of fear of suffering another loss like that of the swine. But the man who had been healed shows indisputable proof of his healing. That he had been healed in his mind is shown by the fact that he now both recognizes Jesus and begs His permission to be with Him. For he was afraid, it would seem, that the demons would again easily assault him when he was separated from Jesus. But the Lord shows him that even if he is not with Jesus, the Lord's grace can shelter him from demonic attack. The Lord says to him, Return to thine own house, and tell what great things God hath done unto thee. By not saying, "what great things I have done unto thee," the Lord gives us an example of humility and teaches us that we should attribute all our accomplishments to God. But though the Lord had commanded him to tell what things God had done for him, he told instead what things Jesus had done for him, so great was his gratitude. Therefore when you do something good for someone, do not desire it to become public knowledge; but he who is the beneficiary of that good deed ought to be moved by gratitude to tell it to others, even though you do not want him to do so.
