New Defender's Study Bible Notes
28:3 stones of darkness. Two different Hebrew words are translated “darkness” in this verse. The “end of darkness” refers to the end of spiritual or moral darkness. The “stones of darkness” refer to stones mined for minerals and metals in the physical darkness below the earth’s surface.
28:3 shadow of death. There are ten references to “the shadow of death” in Job, the first is Job 3:5 and the last in Job 38:17. The best-known reference is in Psalm 23:4. The shadow of death is not actual death, of course, but rather the present danger of death.
