Arcturus

Concise Bible Dictionary:

The word ash or aish has always been a difficult one to translate, the versions differing much; but it is now pretty well agreed that the allusion is not to the star known as Arcturus, but to the constellation known as the Great Bear; his “sons” are supposed to be the stars in the tail of the bear. In the northern hemisphere this constellation is seen all the year round, with its apparent ceaseless motion around the north star, which none but the mighty God can guide (Job 9:99Which maketh Arcturus, Orion, and Pleiades, and the chambers of the south. (Job 9:9); Job 38:3232Canst thou bring forth Mazzaroth in his season? or canst thou guide Arcturus with his sons? (Job 38:32)). It is translated “the Bear” in the RV.
