Having asserted his apostolical authority, he proceeds to claim the rights belonging to his office, especially that of being maintained by it. I. These he states, Co1 9:3-6.

The word implies that they had power over them, and could require their attendance on them, which none could have over any but wives or servants. Now the apostles, who worked for their bread, do not seem to have been in a capacity to buy or have servants to carry with them.
