Constellation

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 Isa. 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."
