The Hebrew noun or (עוֹר) means skin, hide, or leather. It appears over 100 times and carries both literal and highly symbolic theological weight — from the skins God provided in Eden to Job's resurrection hope in the flesh.
After Adam and Eve sinned, God made garments of skin — the first act of divine covering and the first death in Scripture, foreshadowing the sacrificial system (Genesis 3:21). Job's declaration, "after my skin is destroyed, yet in my flesh I shall see God" (Job 19:26), uses or to probe the relationship between bodily existence and resurrection hope.
