“His soul was in Hades, specifically at one time in Paradise, also known as Abraham’s Bosom.”
Where do find that in the Scriptures?
Several passages and doctrine upon doctrine.
Eph 4:9-10, speaks to the descension then ascension.
Also in the Gospels, Luke 23:43.
Hades technically had at least 4 compartments in the Greek description of the underworld, also spoken of in the OT Hebrew as Sheol.
Those 4 compartments were Paradise (also referenced as Abraham’s Bosom) or the place dead believers were placed after the first death, prior to the Incarnation, Cross and Resurrection; the Torments or place for OT unbelievers and unbelievers today until the Great White Throne Judgment; Tartarus, the dark prison of fallen angels with bodies chained spoken of in 1Pet and referenced in Gen 6:1; and the Abyss where criminal fallen angels are imprisoned until the mid-Tribulation release of Abaddon and the army of demons invade the earth.
