Who were the many in Matthew 27:52


Who were the many holy people in Matthew 27:52?  Are these the Old testament saints, like David, Daniel, Moses, Abraham, Jacob, etc?  Are the rest of the Old testament characters in Heaven also?  Was Paradise taken out of Sheol and moved to Heaven at this event?


Matt. 27:52 doesn’t name the Holy People who came out of the grave at the time of the Lord’s resurrection.   Based on Ephes. 4:8 I believe paradise was relocated to heaven at the time of the Lord’s ascension.  Also, in 2 Cor. 12:1-4 Paul used the phrase third heaven, usually a reference to the Throne of God, and paradise interchangeably.
