Destination of the unredeemed soul: Jew v. Gentile…
The destination of a Jew subsequent death is NO different than the destination of a Gentile. If a Jew dies in unbelief having rejected the blood atonement of Yeshua for the forgiveness of sin and the imputation of Messiah’s righteousness by faith, they will initially be interned in Hades-Sheol/Torments (Luke 16) awaiting the Judgment of the Condemned (Revelation 20:10-15) along with every Gentile that has rejected Jesus as Lord.
Every Jew/Israelite who died prior to Messiah’s First-Advent having NOT expressed faith in Yahweh (Hebrews 11), they are currently in Hades-Sheol/Torments (Luke 16) awaiting the Judgment of the Condemned and they will die the “second death” in Hell just as every Gentile who lived apart from faith in God and they will all be “without excuse” in Judgment manifesting subsequent Messiah’s Millennial Reign (Romans 1:20).
The only difference between Jew and Gentile in the coming Judgment of the Condemned will be the enhanced culpability of the Jew concerning “knowledge” (Luke 12:48).
