Ephesians 4:9, says of Jesus: "Now that he ascended, what is it but that he also descended first into the LOWER PARTS OF THE EARTH."
In Acts 2, Peter is speaking, verse 31, " . . . seeing this before spake of the resurrection of Christ, that his soul was not left in HELL"
Matthew 12:40, Jesus Christ says:
"For as Jonas was three days and three nights in the whale's belly: so shall the Son of man be three days and three nights in the HEART OF THE EARTH. "
So His body was in the grave, His spirit was one with the Father, and His soul in Hell til He rose the 3rd day.
