Cetus (mythology) - in The Bible

In The Bible

In Jonah 2:1 (1:17 in English translation), the Hebrew text reads dag gadol (דג גדול), which literally means "great fish." The Septuagint translates this phrase into Greek as mega ketos (μέγα κῆτος). The term ketos alone means "huge fish," and in Greek mythology the term was closely associated with sea monsters. Jerome later translated this phrase as piscis grandis in his Latin Vulgate. However, he translated the Greek word kētos as cetus in Gospel of Matthew 12:40.
