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.
