Arcturus (ark-tû'rus). Job 9:9; Job 38:32, in A. V., but the R. V. correctly reads "bear" in both passages. Arcturus is the name of a fixed star of the first magnitude in the constellation Bootes; but the Hebrew word in Job refers to the constellation Ursa Major, or Great Bear. The "sons" are probably the three stars in the tail of the bear.
