Job 41:28-30

Amplified Bible

²⁸ 
“The arrow cannot make him flee;
Slingstones are treated as stubble by him.
²⁹ 
“Clubs [also] are regarded as stubble;
He laughs at the rushing and the rattling of the javelin.
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).
