Commentary
9 notes on this verseHis bones are as strong pieces of brass: his bones are as bars of iron. Than which nothing is stronger. The repetition is made for greater illustration and confirmation; but what is said is not applicable to the elephant, whose bones are porous and rimous, light and spongy for the most part, as appears from the osteology (k) of it; excepting its teeth, which are the ivory; though the teeth of the river horse are said to exceed them in hardness (l); and artificers say (m) they are wrought with greater difficulty than ivory.

See the strength of his loins
on Job 40:16-19
The description turns to the body, a tail that “sways like a cedar” and bones that “are tubes of bronze”. Gill reads the language as deliberately outsized, likening the parts to trees and metals in place of other animals, too strange for an easy diagram.

His bones are tubes of bronze
His bones are tubes of bronze, and the readings divide on whose bones they are. Aquinas gave them to the elephant, while Gill found elephant bones spongy and gave them to the river horse. Barnes adds that bronze here was likely copper.
The record, by era
The Medieval Church2 voices
Third, he describes the motion of the elephants which are said to have inflexible feet, shin bones and legs in order to sustain the weight of their body, and "they have solid bones without joints." To show this he says, "His bones are like tubes …

His bones are as pipes of brass. His cartilage as plates of iron. 29. In the body they are bones which hold the members together, and members which are held together. This beast then has flesh, it has bones also; because there are some wicked persons, who are yet retained in error by others, and others still more wicked who retain others also in error.
The Puritans and the Awakening1 voice
A humbling challenge which God gave to Job. After he had heaped up many hard questions upon him, to show him, by his manifest ignorance in the works of nature, what an incompetent judge he was of the methods and designs of Providence, he clenches the nail with one demand more, which stands by itself here as the application of the whole.

His bones are as strong pieces of brass-bars of iron - The tusk I have mentioned above is uncommonly hard, solid, and weighty for its size.

On the other hand, Job 40:21, 22 are characteristic of the amphibious river horse. So leviathan (the twisting animal), Job 41:1, is a generalized term for cetacea, pythons, saurians of the neighboring seas and rivers, including the crocodile, which is the most prominent, and is often associated with the river horse by old writers.

His bones are as strong pieces of brass - The circumstance here adverted to was remarkable, because the common residence of the animal was the water, and the bones of aquatic animals are generally hollow, and much less firm than those of land animals. It should be observed here, that the word rendered “brass” in the Scriptures most probably denotes “copper.” Brass is a compound metal, composed of copper and zinc; and there is no reason to suppose that the art of compounding it was known at as early a period of the world as the time of Job. The word here translated “strong pieces” (אפיק 'âphı̂yq) is rendered by Schultens “alvei - channels,” or “beds,” as of a rivulet or stream; and by Rosenmuller, Gesenius, Noyes, and Umbreit, “tubes” - supposed to allude to the fact that they seemed to be hollow tubes of brass. But the more common meaning of the word is “strong, mighty,” and there is no impropriety in retaining that sense here; and then the meaning would be, that his bones were so firm that they seemed to be made of solid metal.
