'Ascending' in the Bible

And he said to him, "Truly, truly I say to all of you, you will see heaven opened and the angels of God ascending and descending upon the Son of Man."

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

Jesus said to her, "Do not touch me, for I have not yet ascended to the Father. But go to my brothers and tell them, 'I am ascending to my Father and your Father, and my God and your God.'"
