“He maketh the deepe to boyle like a pot: hee maketh the sea like a pot of oyntment.”
1611 King James Version (KJV)
41:31 Boil - To swell, and foam, and froth by his strong and vehement motion, as any liquor does when it is boiled in a pot, especially boiling ointment. The sea - The great river Nile, is called a sea, both in scripture, as #Isa 11:15|, and in other authors, as Euphrates is called the sea of Babylon, #Isa 21:1 Jer 51:36|. Lakes also are most frequently called seas both in the Old and New Testament: and in such lakes the crocodiles are as well as in the Nile.
