Job 41:30-32

Amplified Bible

³⁰ 
“His underparts are like sharp pieces of broken pottery;
He moves across and spreads out [grooves] like a threshing sledge on the mire (muddy river banks).
³¹ 
“He makes the deep water boil like a pot;
He makes the sea like a [foaming] pot of ointment.
³² 
“Behind him he makes a shining wake;
One would think the deep to be gray-haired [with foam].
