I think you are confusing borrowing words from greek language and borrowing words from greek mythology. I believe Jesus simply used greek words to convey His message and as I stated before.
Isaiah 66:24 speaks of hell before greek mythology was invented. You have to prove it is not speaking of Hell, not just speculate.
commentaries on Isaiah 66 that support my view:
20–24. Not only will the nations come to my holy mountain Jerusalem during the millennial kingdom, but God promises to take priests and Levites from among them to serve Him. The chapter ends with a wonderful and awful promise of God’s perpetuity. The promise is that the new heavens and the new earth shall remain forever. This will usher in the final state of glorification, which shall be an unchanging state for both the redeemed and the damned. Not only shall the nations worship regularly at Jerusalem during the Millennium, but the people of God throughout all eternity shall come to worship in the New Jerusalem. All flesh refers to all of the redeemed of the Lord. These alone shall come to worship … the Lord. Isaiah’s universalism is not a message of universal salvation regardless of one’s faith, but a universal kingdom with the wicked purged out of it! Thus, the book ends with the awesome statement that the redeemed shall go forth, and look upon the carcases of the men that have transgressed against me. While the imagery may be drawn from the fact that one could stand in the Temple at Jerusalem and look down into the valley of Hinnom (from which the imagery for hell is drawn), nevertheless, the scene here seems rather to be that of the redeemed of heaven, in their final, glorified, and fixed state. Those who are described as suffering are undoubtedly in the lake of fire where their worm shall not die, neither shall their fire be quenched (Mk 9:44; Rev 20:14–15). The question is often asked of this statement as to whether or not the saved will be able to see those who are in hell. The obvious answer is, Yes! In our final and fixed state, we would be able to see our dearest loved one in the lake of fire and be able to say, “The judge of all the earth has done right!” In our finite human state we could never bear such a sight. The awesome closing of this marvelous book of prophecy is a reminder to every believer of our responsibility to personal witnessing and soul-winning. There is a real hell to be avoided, and all those who do not receive Jesus Christ as their personal Saviour shall go there. Of these awesome words, S. C. Thexton, Isaiah 40–66, pp. 154–155, said “They remind us that from the gate of Heaven there is a road to Hell, and that before every man there lies the choice between the way of life and the way of death.”
Thus, the book of Isaiah ends much as it began, with a message of both impending doom and potential deliverance. In this greatest of the Old Testament prophets we see one recurring theme: Jesus Christ, the Virgin’s son, Immanuel, the Branch of the Lord, the Mighty God, the Prince of Peace, the coming Messiah, the Suffering Servant, the glorious King! “To him give all the prophets witness …” (Acts 10:43).

66:22-24. Israel will be as enduring as the new heavens and the new earth (see comments on 65:17). All mankind (i.e., people from all nations) will worship the Lord, bowing down before Him. As Isaiah had frequently written, these righteous ones will contrast greatly with those who rebelled (pāša‘; see comments on 1:2) against the Lord . They will suffer eternal torment (cf. Mark 9:48). This awesome way in which the majestic Book of Isaiah concludes points to the need for unrepentant people to turn to the Lord, the only God, the Holy One of Israel.

The good news is that a person can escape these eternal fires of hell by putting his or her faith in the Savior, the Servant of the Lord that Isaiah has described so winsomely in so many of his prophecies.
For most of our readers, who have already received Christ as their Savior, the Book of Isaiah is great prophecy and great poetry—certainly among the finest in the OT. But it would be a shame if that were all. We are meant to apply this book to our daily lives and practice God’s good pleasure.
We close with a practical exhortation from the devout English Bible scholar, W. E. Vine:

Luther:
Their worm shall not die. They have been consigned to eternal fire. This text, known well enough from Mark 9:48, states that the ungodly Jews are condemned forever. They have their existence here as dead bodies. So we see an unquenchable fire and an undying worm. The bite of the conscience is in truth that worm. Sin is the worm that bites day and night. Afterwards comes the fire. And they shall be an abhorrence to all flesh. The damned are a nauseating and revolting sight to the believers, like the Jews, papists, and Enthusiasts. Final conclusion: Let those who will not believe depart into these endless ills of which the prophet speaks.
