I have argued in The Coming of the Son of Man (91-94) and frequently on this blog that in Jesus’ teaching the Greek word geenna, which is usually erroneously translated “hell”, signifies not a general “place” of punishment of sinners after death but divine punishment of Jerusalem by means of military invasion.
The argument is quite straightforward: Jesus believed that in the absence of national repentance his people faced the destruction of war (cf. Matt. 22:7; Lk. 21:20); Jeremiah warned the inhabitants of Jerusalem that because of the evil that they had done in the sight of the Lord they would fall by the sword when the Babylonians invaded, and the bodies of the dead would be thrown into the Valley of the Sons of Hinnom (Jer. 7:32-34; 19:10-11); Josephus later describes how during the Roman siege the Jews were compelled to throw the dead over the walls of the city into the surrounding valleys for lack of space to bury them (Jos. War 5.12.3); so it seems highly likely that Jesus intended to make the same point. I think the argument is exegetically sound and makes a lot of sense as part of a narrative-historical reading of the New Testament.
Mitchell Powell, however, asks a pertinent question: “who is the earliest recorded reader of the New Testament you know of to advocate such a view?” Well, I have to say that to the best of my knowledge it appears to be very much a minority position.
