Three principle brothers undertook the writing of the Watchtower Society publication “Aid to Bible Understanding” in 1967. This 1,696 page Bible encyclopedia and reference work was an enormous undertaking, representing many thousands of man-hours of intense study. It took three brothers working on it full time about five years to complete, and was released in 1971.
