Leviathan was not referenced in the Bible as a dinosaur - Leviathan, serpent and Satan are used interchangable. Most people understand Leviathan of Job 41 to be a whale.

Both the behemoth and leviathan are given as examples in Job of evil that only God can overcome.


Word Origin & History
behemoth

late 14c., huge biblical beast (Job xl.15), from L. behemoth , from Heb. b'hemoth, usually taken as plural of intensity of b'hemah "beast." But the Heb. word is perhaps a folk etymology of Egyptian pehemau , lit. "water-ox," the name for the hippopotamus.

Behemoth definition

(Job 40:15-24). Some have supposed this to be an Egyptian word meaning a "water-ox." The Revised Version has here in the margin "hippopotamus," which is probably the correct rendering of the word. The word occurs frequently in Scripture, but, except here, always as a common name, and translated "beast" or "cattle." http://dictionary.reference.com/browse/behemoth

So we have the hippo and the whale - neither of which are dinosaurs.

When we walk in the darkness it's easy to be deceived. In the dark we've gotta go by our senses. But when we walk in the light we can penetrate the darkness and see what surrounds us. It makes it harder to be deceived.
