Eusebius of Caesarea
Catena Aurea · Lukasevangelium 9
Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases. And he sent them to preach the kingdom of God, and to heal the sick. And he said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece. And whatsoever house ye enter into, there abide, and thence depart. And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them. And they departed, and went through the towns, preaching the Gospel, and healing every where.
Wishing then that they should be free from the desire of wealth and the anxieties of life, He gave this injunction. He took it as a proof of their faith and courage, that when it was commanded them to lead a life of extreme poverty, they would not escape from what was ordered. For it was fitting that they should make a kind of bargain, receiving these saving virtues to recompense them for obedience to commands. And when He was making them soldiers of God, He girds them for battle against their enemies, by telling them to embrace poverty. For no soldier of God entangles himself in the affairs of a secular life. (2 Tim. 2:4.)
