And not the 1st scripture to support that...because there are none...
Hellfire has it origins in pagan beliefs...
In ancient Babylonian and Assyrian beliefs the “nether world . . . is pictured as a place full of horrors, and is presided over by gods and demons of great strength and fierceness.” (The Religion of Babylonia and Assyria, Boston, 1898, Morris Jastrow, Jr., p. 581) Early evidence of the fiery aspect of Christendom’s hell is found in the religion of ancient Egypt. (The Book of the Dead, New Hyde Park, N.Y., 1960, with introduction by E. A. Wallis Budge, pp. 144, 149, 151, 153, 161) Buddhism, which dates back to the 6th century B.C.E., in time came to feature both hot and cold hells. (The Encyclopedia Americana, 1977, Vol. 14, p. 68) Depictions of hell portrayed in Catholic churches in Italy have been traced to Etruscan roots.—La civiltà etrusca (Milan, 1979), Werner Keller, p. 389.
But the real roots of this God-dishonoring doctrine go much deeper. The fiendish concepts associated with a hell of torment slander God and originate with the chief slanderer of God (the Devil, which name means “Slanderer”), the one whom Jesus Christ called “the father of the lie.”—John 8:44.

The early Christians did not believe in the hell doctrine...it was introduced in the 2nd century AD as a result of blending with Greek philosophy...

Sheol/Hades/hell means the grave, nothing more...even wiki acknowledges that...
While these three terms are translated in the KJV as "hell" these three terms have three very different meanings.
Hades has similarities to the Old Testament term, Sheol as "the place of the dead" or "grave". Thus, it is used in reference to both the righteous and the wicked, since both wind up there eventually.[48]
Gehenna refers to the "Valley of Hinnom", which was a garbage dump outside of Jerusalem. It was a place where people burned their garbage and thus there was always a fire burning there. Bodies of those deemed to have died in sin without hope of salvation (such as people who committed suicide) were thrown there to be destroyed.[49] Gehenna is used in the New Testament as a metaphor for the final place of punishment for the wicked after the resurrection.[50]
Tartaróō (the verb "throw to Tartarus", used of the fall of the Titans in Illiad 14.296) occurs only once in the New Testament in II Peter 2:4, where it is parallel to the use of the noun form in 1 Enoch as the place of incarceration of the fallen angels. It mentions nothing about human souls being sent there in the afterlife.
