"Alcyone, the central one of the renowned Pleiadic stars… Alcyone, then, as far as science has been able to perceive, would seem to be ‘the midnight throne’ in which the whole system of gravitation has its seat, and from which the Almighty governs his universe…"
*** Reconciliation 1928 p.14 ***
"The constellation of the seven stars forming the Pleides… It has been suggested, and with much weight, that one of the stars of that group is the dwelling-place of Jehovah… The constellation of the Pleiades is a small one compared with others… But the greatness in size of other stars or planets is small when compared with the Pleiades in importance, because the Pleiades is the place of the eternal throne of God."
*** Watchtower 1953 November 15 p.703 Questions from Readers ***
"To just what stars or star groups these names refer we do not know today. Hence it is useless to indulge in unprofitable speculations. Incidentally, Pleiades can no longer be considered the center of the universe and it would be unwise for us to try to fix God’s throne as being at a particular spot in the universe. Were we to think of the Pleiades as his throne we might improperly view with special veneration that cluster of stars.-Deut. 4:19; 2 Chron. 2:6; 6:18."
