Job 41:27

His heart is as firm as a stone,

yes, firm as the lower millstone.

When he raises himself up, the mighty are afraid.

They retreat before his thrashing.

If one attacks him with the sword, it can’t prevail;

nor the spear, the dart, nor the pointed shaft.

The arrow can’t make him flee.

Sling stones are like chaff to him.

Clubs are counted as stubble.

He laughs at the rushing of the javelin.

His undersides are like sharp potsherds,

leaving a trail in the mud like a threshing sledge.
