"Seeing it is a just thing with God to repay tribulation to them that trouble you: And to you who are troubled, rest with us when the Lord Jesus shall be revealed from heaven, with the angels of his power: In a flame of fire, giving vengeance to them who know not God, and who obey not the gospel of our Lord Jesus Christ. Who shall suffer eternal punishment in destruction, from the face of the Lord, and from the glory of his power: When he shall come to be glorified in his saints, and to be made wonderful in all them who have believed; because our testimony was believed upon you in that day."
As I have stated in other posts, the second death will be eternal (everlasting) death (destruction) and eternal separation from God. Here are eight different translations for you and I believe they all say the same. Eternal (everlasting) death (destruction) with no hope of a physical resurrection. I cannot see any eternal fiery Hell in these words.
The Douay-Rheims also says Eternal destruction. The punishment is eternal separation from God. This does not say eternal agony in the flames of Hell.
