He descended, bearing our sins and iniquities upon His soul/Person. His Spirit ascended, His soul/Person descended.
He was three days and three nights in the belly of the earth....
He fulfilled the Scripture in that all sin was ascribed to Azazel, who is the chief rebel Watcher angel chained, with his fallen watcher angel company, in the lowest compartment of Sheol.
The name of that rebel Watcher is translated "scapegoat", in error, but on the day of Atonement rehearsal all sin was laid on the goat elected by lot "to Azazel", and that goat was sent away alive, to go "to Azazel" who is bound in the "wilderness", which is Sheol.
The goat elected by lot "to YHWH" was offered on the altar as a sacrifice to YHWH, and the smoke of it ascended, "To YHWH".
On the day of Atonement's fulfillment once for all, by the Kinsman Redeemer, His One Living Spirit ascended to the Father; His soul/Person departed His body and went away, bearing our sins and iniquities that the Father laid on Him, and His body was laid in a tomb, not suffering corruption for three days and nights, for it was not possible to corrupt that flesh, for in His flesh of New Man creation there was no sin and "Satan had nothing in Him", as He said.
He proclaimed the fulfilled Atonement in Sheol, below. He then took all the captives out of there to heaven above, whose souls were held in the comfortable compartments in Sheol until that Day of Atonement. Those compartments in the belly of the earth were made for them to reside in, and Enoch was shown them, and they had to go there to await the Atonement promised in Genesis 3. Enoch was shown the souls of those who were held there, and was shown the four different compartments there.
The souls/persons who had to wait there for the promised Day of Atonement were there because we all died the first death of separation to the Father of Glory while we were the seed of the entire race of Adam, created to come forth in our season, residing in the loins of our first father, the head of the race of Adam .
Since the fall of our first father, Adam, no human being could ascend to the Father of Glory until the Acceptable Atonement was fulfilled once, for all (for whosoever will); and for all who are slain in the womb or die before they are accountable for understanding right or wrong, by their own will.
Jesus rose without the sin He went away bearing. He gave/ascribed all that sin He bore, "To Azazel" on that "Acceptable Day", and that is the teaching of the Torah in the rehearsals of that day of Atonement.
Enoch first told that all sin would be given "To Azazel" in the 70th generation, and Moses was given the rehearsal of that sending away of the elected goat , bearing those sins, "To Azazel"...
Tis a pity the English translators of the Hebrew did not know, or willfully hid, the meaning of the Day of Atonement, in that "to Azazel" all sin would be ascribed in the 70th generation, and that Azazel & Co were the spirits chained in Sheol since the flood, in chasm's called "a barren wilderness", in the belly of the earth, as Enoch reveals.
Azazel will be tormented along with his company of fallen watcher angels in the Lake of Fire forever and forever for falling for the lies of the satans (there are many evil spirits called the satans, with one chief), and tormented for the sin of the Adam father of our kind, which is now covered by the Atonement promised, for all born in Adam, and "whosoever will", who are born as the seed of the first father of our kind can call on the name of the LORD and be saved, for "He took our sins away", to whosoever believes and receives.
