Job 41:28

The arrow cannot make him flee ,.... The skin of the crocodile is so hard, as Peter Martyr says, that it cannot be pierced with arrows, as before observed; therefore it is not afraid of them, nor will flee from them;

slingstones are turned with him into stubble ; are no more regarded by him than if stubble was cast at him; not only stones out of a sling, but out of an engine; and such is the hardness of the skin of the crocodile, that, as Isidore says F5 Origin. l. 12. c. 6. , the strokes of the strongest stones are rebounded by it, yea, even it is said to withstand against musket shot F6 Mandelsloe in Harris's Voyages, &c.; vol. 1. p. 759. .
