Second in the list of Demons in Behemoth. There's some controversy as to whether Behemoth is a demon or not, or even a mundane animal. The passage that calls this into question is "He [is] the chief of the ways of God:" Still, according to the Dictionnaire Infernal, Behemoth is classified along with the other demons.
From Wikipedia:
Behemoth is the name of a creature mentioned in the Book of Job, 40:15-24. In Hebrew it can be rendered as בהמות, Bəhēmôth, Behemot, B'hemot; in Arabic بهيموث (Bahīmūth) or بهموت (Bahamūt) .
The word is most likely a plural form of בהמה (bəhēmāh ("animal")). It may be an example of pluralis excellentiae, a Hebrew method of expressing greatness by pluralizing a noun; it thus indicates that Behemoth is the largest and most powerful animal.
Metaphorically, the name has come to be used for any extremely large or powerful entity.
The text from the Book of Job 40 (King James Version Bible) is as follows:
15 Behold now behemoth, which I made with thee; he eateth grass as an ox.
16 Lo now, his strength [is] in his loins, and his force [is] in the navel of his belly.
17 He moveth his tail like a cedar: the sinews of his thighs are wrapped together.
18 His bones [are as] strong pieces of brass; his bones [are] like bars of iron.
19 He [is] the chief of the ways of God: he that made him can make his sword to approach [unto him].
20 Surely the mountains bring him forth food, where all the beasts of the field play.
21 He lieth under the shady trees, in the covert of the reed, and fens.
22 The shady trees cover him [with] their shadow; the willows of the brook compass him about.
23 Behold, he drinketh up a river, [and] hasteth not: he trusteth that he can draw up Jordan into his mouth.
24 He taketh it with his eyes: [his] nose pierceth through snares.
