(The Lord speaking is red text)
It shall devour the strength of his skin: [even] the firstborn of death shall devour his strength.
disease eats away at his skin; the first stages of death devour him gradually.
It devours patches of his skin; the firstborn of death devours his limbs.
The members of his body shall be devoured, Yea, the first-born of death shall devour his members.
It shall devour{H398} the strength{H905} of his skin{H5785}: even the firstborn{H1060} of death{H4194} shall devour{H398} his strength{H905}.
The Book of Job is a profound exploration of suffering and faith, and Job 18:13 is a part of Bildad's speech, one of Job's friends who come to comfort him during his severe afflictions. Bildad is a representative of the retributive justice theory, which posits that good is rewarded and evil is punished, often in this life. In the historical context, this belief was common in the ancient Near East and is reflected in much of the wisdom literature of the time.
In Job 18:13, Bildad uses vivid imagery to describe the fate of the wicked, suggesting that calamity will consume the very vitality of the wicked person's body. The phrase "the strength of his skin" implies a total destruction that penetrates to the outermost defenses of a person, leaving nothing untouched. The "firstborn of death" is a poetic way of speaking about the most severe and primary consequence of sin, which Bildad believes is death itself. In his view, the wicked can expect nothing less than complete ruin, as death claims its due.
The themes of this verse include the nature of suffering, divine retribution, and the belief that moral order will ultimately prevail. Bildad's words are meant to warn Job that his suffering might be a result of wrongdoing, and that he should repent to avoid further calamity. However, the book as a whole challenges this simplistic understanding of suffering, as Job's afflictions are not a direct result of his sinfulness. Instead, the Book of Job delves into the complexities of human suffering and the mystery of God's ways, questioning the adequacy of human wisdom to comprehend the divine perspective on human pain and misfortune.
