Hebrews Kesil; i.e., "the fool", the name of a constellation (Job 9:9; 38:31; Amos 5:8) consisting of about eighty stars. The Vulgate renders thus, but the LXX. renders by Hesperus, i.e., "the evening-star," Venus. The Orientals "appear to have conceived of this constellation under the figure of an impious giant bound upon the sky." This giant was, according to tradition, Nimrod, the type of the folly that contends against God. In Isaiah 13:10 the plural form of the Hebrew word is rendered "constellations."

Noah Webster's New International Dictionary of the English Language

(n.) A large and bright constellation on the equator, between the stars Aldebaran and Sirius. It contains a remarkable nebula visible to the naked eye.
