The biblical entry where Behemoth is mentioned in a speech from the mouth of God in chapter 40 of the Book of Job, a primeval creature created by God and so powerful that only God can overcome him:
15 Behold, Behemoth, which I made as I made you; he eats grass like an ox.
16 Behold, his strength in his loins, and his power in the muscles of his belly.
17 He makes his tail stiff like a cedar; the sinews of his thighs are knit together.
18 His bones are tubes of bronze, his limbs like bars of iron.
19 He is the first of the works of God; let him who made him bring near his sword!
20 For the mountains yield food for him where all the wild beasts play.
21 Under the lotus plants he lies, in the shelter of the reeds and in the marsh.
22 For his shade the lotus trees cover him; the willows of the brook surround him.
23 Behold, if the river is turbulent he is not frightened; he is confident though Jordan rushes against his mouth.
24 Can one take him by his eyes, or pierce his nose with a snare? (Job 40:15-24, ESV)
The passage pairs Behemoth with the sea-monster Leviathan, both composite mythical creatures with enormous strength which humans like Job could not hope to control, yet both reduced to the status of divine pets.
The Hebrew word behemoth has the same form as the plural of the Hebrew noun בהמה behemah meaning 'beast', suggesting an augmentative meaning 'great beast'. However, some theorize that the word might originate from an Egyptian word of the form pꜣ jḥ mw 'the water-ox' meaning 'hippopotamus', altered by folk etymology in Hebrew to resemble behemah. However, this phrase with this meaning is unattested at any stage of Egyptian.
