An everlasting Hell where souls were tormented for millions upon billions upon trillions of years was not known in the Old Testament. Yet the destruction of the soul of the wicked was.
4: Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: th
e soul that sinneth, it shall die. Ezekiel 18:4
This was the same doctrine taught by Yeshua.
28: And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to
destroy both
soul and body in hell. Matt. 10:28
This fire judgment is shown us in Malachi.
16: Then they that feared the LORD spake often one to another: and the LORD hearkened, and heard it, and a book of remembrance was written before him for them that feared the LORD, and that thought upon his name.
17: And they shall be mine, saith the LORD of hosts, in that day when I make up my jewels; and I will spare them, as a man spareth his own son that serveth him.
18: Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
1: For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the LORD of hosts, that it shall leave them neither root nor branch. Mal. 1:1
This is the reference Yeshua had in mind:
40: As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world.
41: The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;
42: And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Matt. 13:40-42
The "furnace of fire" Yeshua mentioned sounds a lot like Malachi's fiery oven. The "tares" sound a lot like Malachi's "stubble".
