Sounds like the Elijah hand off to Elisha concept they gave regarding in 1942. Other "analogies" Naomi to Ruth.

In 1942 the change came. In the throes of World War II, with the change in administrations of the second and third presidents of the Watch Tower Bible and Tract Society, the Elijah work passed away, having realized its purpose to Jehovah’s praise. It had been actively directed toward beginning the work of "dividing the waters" of the symbolic Jordan River, that is, dividing the symbolic waters of the peoples, gathering the "other sheep" or "great crowd" to the right hand of the reigning King Jesus Christ. (2 Ki. 2:8; Matt. 25:31-46) As the Elisha class vigorously took up the "mantle of Elijah" or the divine commission Elijah had so actively fulfilled, the time for unparalleled expansion had begun. The years since 1942 have told their tale regarding the exploits of the anointed Elisha class, accompanied by an ever-increasing number of the "great crowd."—Rev. 7:9-17.
To parallel the many miracles performed by the original Elisha, sixteen as compared with Elijah’s eight, the modern Elisha class at once began arrangements for producing better preachers of the Kingdom good news in furtherance of the prophecy of Matthew 24:14. On February 1, 1943, the Watchtower Bible School of Gilead was set up for training missionaries and special representatives of the Watch Tower Society to serve in all parts of the earth. That same year, 1943, a new training program, the Theocratic Ministry School, began in the congregations of Jehovah’s witnesses. At first only male students were enrolled in these schools, but in 1958 provision was made for the women of the congregations to enroll and participate.
