The correct answer to "Where is Jehovah" based on various WT publications is in the Pleiades Galaxy:
The Golden Age September 10, 1924, pages 793 & 794:"... the position of the Pleiades at the time of the completion of the Great Pyramid of Egypt, "God's Stone Witness," is a very prominent feature of that building in the midst of the land of Egypt. For these and other reasons Bible Students have good cause to believe that in the region of the Pleiades is located the throne of Jehovah God..."
The book Reconciliation in 1928 (J.F. Rutherford) on page 14:"The constellation of the seven stars forming the Pleiades appears to be the crowning center around which the known systems of the planets revolve.... It has been suggested, and with much weight, that one of the stars of that group is the dwelling place of Jehovah and the place of the highest heavens…The constellation of the Pleiades is a small one compared with others which scientific instruments disclose to the wondering eyes of man. But the greatness in size of other stars or planets is small when compared to the Pleiades in importance, because the Pleiades is the place of the eternal throne of God."
