Mazzaroth (Hebrew Transliteration: מַזָּרוֹת Mazzārōṯ, LXX Μαζουρωθ, Mazourōth) is a Biblical Hebrew word found in the Book of Job (Job 38:32) whose precise meaning is uncertain. Its context is that of astronomical constellations, and some judge it to mean a specific constellation, while it is often interpreted as a term for the zodiac or the constellations thereof.[1][2] The similar word mazalot (מַּזָּלוֹת) in 2 Kings 23:3–5 may be related.
According to 10th-century biblical exegete Saadia Gaon, it literally means "constellations," [3] while others interpret the word as naming various concrete astronomic bodies - Saturn, the seven planets, the Hyades, the Northern and Southern Crowns, the Southern Ship (Argo Navis?) or Sirius.[1]
The word itself is a hapax legomenon (i.e., a word appearing only once in a text) of the Hebrew Bible. In Yiddish, the term mazalot came to be used in the sense of "astrology" in general, surviving in the expression "mazel tov," meaning "good fortune."[4]
