Robbery

2 Corinthians 11:8 KJV
I robbed other churches, taking wages of them, to do you service.

Paul admits that when he worked among the Corinthians, though they were in a richer city, he did not take wages of them but "robbed other churches." This is not meant in the criminal sense but as a matter of illustration. Paul received gifts of support from those churches he had founded, and perhaps some others to.

Now he speaks to the Corinthians and reminds them - though the laborer is worthy his hire, he did not require it of them. He said he would continue his practice, making evident that it was neither criminal nor unethical. But it does emphasize a point; those who live off of the gifts of others should not expect that those gifts are theirs to do with wantonly.
• Those who accept gifts for their ministries
• Those who ask for gifts for various purposes, even
• Those who receive gifts to meet personal needs 
ought to view those gifts as "robbery."

Some other need has gone unmet because the money was given to them.

It is an enormous sacrifice that others would give. That should never be taken for granted.
