John Trapp on Job 41:22

Verſe 22. In his neck remaineth ſtrength] Ariſtotle ſaith, that among Fiſhes,De part [illegible: 1 word] lib. 3. the Dolphin, Whale, and ſuch as breath; have necks proportionable to their bodies. The word rendred remaineth, is in the Hebrew, lodgeth, or abideth all night: ſo ſpoken, ſaith One, becauſe the Whale, as alſo the Dolphin, ſleepeth with his head erected above water.

And ſorrow is turned into joy before him] i.e. He knows no ſorrows, he fears no hurt, but alwayes rejoyceth, bearing himſelf bold upon his ſtrength, God having made him to ſport in the ſea, Pſal. 104.26. Others read it, And before him danceth fear; Pavor & Pallor, (Tullus Hoſtilius his two gods) men dance, or ſtart for fear.
