Jesus sent out seventy on one occasion. Was Paul not feeding the Gentiles, along with his many named helpers ? not a small group.
Jesus also said they would be witnesses of HIM, not a GB in Jerusalem, or big J, but him, to the ends of the earth. All such witnesses would be "feeding" their listeners. To be accomplished such a work would involve many many people.
If JW's cannot see through this utter tripe then there is no hope, they will remain in the cult till they die.
