There is no record of Jesus being anywhere other than the grave after his death and before God resurrected him. I am inclined to believe the evidence of Scripture on this point. Jesus was dead, his soul was in the grave.
So if someone is in the grave, Hades, then that means they are dead right? They aren't living anymore.
Acts 2
27because
You will not abandon my soul to Hades,
nor will You let Your Holy One see decay.
31Foreseeing this, David spoke about the resurrection of the Christ, t
hat He was not abandoned to Hades, nor did His body see decay.
