The Old Testament (in the KJV) has several references to dragons which the NIV changes to 'jackals' (for example Job 30:29), or 'serpents'-'cobras' (Deuteronomy 32:33), or in one case 'monster' (Isaiah 27:1). It refers to wild creatures living in desert places rather than fictitious supernatural beasts.

In the New Testament book of Revelation, which is in the most part a book of symbol, the original Greek word drakon is transliterated as dragon-an imaginary creature with seven heads and ten horns, representing evil human activity.

"Then the dragon was enraged at the woman and went off to make war against the rest of her offspring-those who obey God's commandments and hold to the testimony of Jesus." (Revelation 12:17).
