In everything I [Paul] did, I showed you that by this kind of hard work we must help the weak, remembering the words the Lord Jesus himself said: “It is more blessed to give than to receive.” Acts 20:35
“These words are spoken to the leaders of the church so that, in addition to other things, they might judge themselves imitators of Paul by refusing to accept money. This is quite obvious from the words that follow: “I have given you an example in all things that those who toil must come to the help of the weak” and provide for them. If the words should be remembered, they will provide the principle: “It is better to give than to receive.”
