2023-33_Evangelism - Sheol Hades Hell Part 3 of 3

OT Sheol, NT Hades and then Jesus Christ on Hell (Gehenna/geenna). Does Sheol and Hades give specific references to the afterlife, resurrection, spiritual realm or are these places physical places of the body? What about hell/gehenna, is that a physical or spiritual place and is it eternal? Who goes there? Jesus spoke of Hell on the Sermon on the Mount, should we when we evangelize?
