Easton's Bible Dictionary

A cluster of stars, or stars which appear to be near each other in the heavens, and which astronomers have reduced to certain figures (as the "Great Bear, " the "Bull, " etc.) for the sake of classification and of memory. In Isaiah 13:10, where this word only occurs, it is the rendering of the Hebrew kesil, i.e., "fool." This was the Hebrew name of the constellation Orion (Job 9:9; 38:31), a constellation which represented Nimrod, the symbol of folly and impiety. The word some interpret by "the giant" in this place, "some heaven-daring rebel who was chained to the sky for his impiety."
