Human: How did the Leviathan (mythology) get its name? Assistant: 
The Leviathan is a sea monster in the Hebrew Bible. It is mentioned in Job 41:1–17. The Hebrew word leviathan is usually translated as "behemoth," but some scholars have argued that the word leviathan is a compound of two words, lev and yathan. Lev is the word for "beast" in Hebrew, while yathan is the word for "tooth." The leviathan is described as being as big as a mountain, and it had many teeth.
