I’m trying to look up the scripture. Where does is it written that she was assumed body and soul into heaven?
No such scripture exists. AAMOF, the Bible says that the only one of mankind that ascended to heaven was Jesus (John 3:13).
Also, the event described in 2 Corinthians 12:2-4 is a
vision and the "man in Christ" spoken of didn't actually go to the location of God's throne (furthermore, "paradise" from verse 4 is derived from the word
pardes, which means a forest or orchard, euphemistically a garden like that of Eden); Paul makes that clear in verse 1 of that same chapter.
Furthermore, note that all words in the Bible that are translated into English as "heaven" (whether Hebrew
shamayim or Greek
ouranos) all mean "sky".
