This is the "fire":
Isaiah 24:5-6, "5 For the earth has been defiled under its inhabitants, because they have transgressed the Torah, changed the law, broken the everlasting covenant. 6 Therefore a curse shall consume the earth, and those who dwell in it be punished. Therefore the inhabitants of the earth shall be burned, and few men shall be left.”
Matt 24:21-22, "For then will be great tribulation, such as has not come to pass since the beginning ofthe world to this time--no, nor ever will be. And unless those days were shortened, there would no flesh be saved; but for the elect's sake, those days will be shortened."
Malachi 4:1-6, "4:1, "“For look, the day shall come, burning like a furnace, and all the proud, and every wrongdoer shall be stubble. And the day that shall come shall burn them up,” said יהוה of hosts, “which leaves to them neither root nor branch."4:2, "“But to you who fear My Name the Sun of Righteousness shall arise with healing in His wings. And you shall go out and leap for joy like calves from the stall."4:3, "“And you shall trample the wrongdoers, for they shall be ashes under the soles of your feet on the day that I do this,” said יהוה of hosts."4:4, "“Remember the Torah of Mosheh, My servant, which I commanded him in Ḥorĕḇ for all Yisra’yl – laws and right-rulings."4:5, "“See, I am sending you Ěliyah the prophet before the coming of the great and awesome day of יהוה."4:6, "“And he shall turn the hearts of the fathers to the children, and the hearts of the children to their fathers, lest I come and strike the earth with utter destruction.” (Zec 14:13)
