It was a Jewish custom, and held no disgrace, according to the manners of the people of old, for women to minister of their substance, food, and clothing to their teachers. This Paul says, that he refused, because it might occasion scandal among the Gentiles. They ministered to the Lord of their substance, that He might reap their carnal things, of whom they reaped spiritual things. Not that the Lord needed food of the creature, but that He might set an example for the teacher, that He should be content to receive food and clothing from His disciples.
But let us see what sort of attendants He had; “Among whom was Mary Magdalene , and Mary the mother of James and Joseph, and the mother of Zebedee’s children.”
