This past WT study (October 15, 2015, Serve Jehovah without Distractions), which focuses on doing more for Jehovah in paragraph 17 states,
17 Consider a Welsh couple, Mark and Claire, each of whom entered the pioneer service after completing school and continued pioneering after they got married. “We were able to simplify our lives further by giving up our three-bedroom house and our part-time work so that we could enter the international construction work,” explains Mark. For the past 20 years, they have traveled throughout Africa, helping to build Kingdom Halls. Once, their personal funds dropped to 15 dollars, but Jehovah took care of them. “It gives us deep satisfaction,” says Claire, “to spend every day serving Jehovah. We have made so many friends along the way, and we lack nothing. The little that we have given up cannot be compared to the happiness that comes from serving Jehovah full-time.” Many full-time servants have had similar experiences.#
There's also a reference article that states,
After a two-day journey by train, we reached our assignment in Tiruchchirappalli, a city in the southern state of Madras (now Tamil Nadu). There, we joined three Indian special pioneers who were witnessing to a population of 250,000 people. Living conditions were primitive. At one time, we had less than $4 (U.S.) left in our pockets. But when that money ran out, Jehovah did not forsake us. One person who was studying the Bible lent us money to rent a home suitable for holding meetings. Once when we were low on food, a neighbor kindly brought us some homemade curry. I loved it, but it was so spicy hot that it gave me hiccups!
It's interesting that Jehovah used a non witness to provide for his servants.
