Arcturus
   bear-keeper, the name given by the ancients to the brightest
   star in the constellation Bootes. In the Authorized Version (Job
   9:9; 38:32) it is the rendering of the Hebrew word _'ash_, which
   probably designates the constellation the Great Bear. This word
   ('ash) is supposed to be derived from an Arabic word meaning
   night-watcher, because the Great Bear always revolves about the
   pole, and to our nothern hemisphere never sets.
