American Tract Society Bible Dictionary
Answers, in the English Bible, the Hebrew word signifying a sea-monster, huge serpent, etc. Thus in Deuteronomy 32:33 Jeremiah 51:34 Revelation 12:1-17 , it evidently implies a huge serpent; in Isaiah 27:1 51:9 Ezekiel 29:3 , it may mean the crocodile, or any large sea-monster; while in Job 30:29 Lamentations 4:3 Micah 1:8 , it seems to refer to some wild animal of the desert, most probably the jackal. The animal known to modern naturalists under the name of dragon, is a harmless species of lizard, found in Asia and Africa.
