'Ascending' in the Bible

He continued, "I tell all of you the solemn truth -- you will see heaven opened and the angels of God ascending and descending on the Son of Man."

Then what if you see the Son of Man ascending where he was before?

Jesus replied, "Do not touch me, for I have not yet ascended to my Father. Go to my brothers and tell them, 'I am ascending to my Father and your Father, to my God and your God.'"
