Job 6:12

“[Is] my strength the strength of stones? etc.] Is it like such especially which are foundation and corner stones that support a building? or like a stone pillar, that will bear a prodigious weight? no, it is not: or [is] my flesh of brass? is it made of brass? or is it like to brass for hardness, or for sustaining any weight laid on it? it is not; and, therefore, it cannot bear up under the ponderous load of afflictions on it, but must sink and fail; it is but flesh and blood, and that flesh like grass, weak and feeble; and, therefore, death is better than life laden with such an insupportable burden.”

“Disease had so attacked him that his strength would need to be hard as a stone, and his flesh like brass, not to sink under it. But he has only flesh, like other men. It must, therefore, give way; so that the hope of restoration suggested by Eliphaz is vain (see on Job 5:11).”

“Is my strength the strength of stones? - That is, like a rampart or fortification made of stones, or like a craggy rock that can endure assaults made upon it. A rock will bear the beatings of the tempest, and resist the floods, but how can frail man do it? The idea of Job is, that he had no strength to bear up against these accumulated trials; that he was afraid that he should be left to sink under them, and to complain of God; and that his friends were not to wonder if his strength gave way, and he uttered the language of complaint. Or is my flesh of brass? - Margin, “brazen.” The comparison used here is not uncommon. So Cicero, Aca. Qu. iv. 31, says, Non enim est e saxo sculptus, ant e…”

“Is, &c. - I am not made of stone or brass, but of flesh and blood, as others are, therefore I am unable to endure these miseries longer, and can neither hope for. nor desire the continuance of my life. Job 6:13”

“of brass: Heb. brasen, Job 40:18, Job 41:24 Job 6:13”
