From Hos 13:14, a free version of the Sept.: “Where is thy penalty, O Death? Where thy sting, O Hades? Heb.: Where are thy plagues, O Death? Where thy pestilence, O Sheol?
O grave (ἅδη)
Which is the reading of the Septuagint. The correct reading is θάνατε O death. So Rev. Hades does not occur in Paul's writings. In Rom 10:7 he uses abyss. Edwards thinks that this is intentional, and suggests that Paul, writing to Greeks, may have shunned the ill-omened name which people dreaded to utter. So Plato: “People in general use the word (Pluto) as a euphemism for Hades, which their fears lead them to derive erroneously from ἀειδής the invisible” (“Cratylus,” 403).
Sting (κέντρον)
In the Septuagint for the Hebrew pestilence. See on Rev 9:9. The image is that of a beast with a sting; not death with a goad, driving men.
