'Ascending' in the Bible

He dreamed. Behold, a stairway set upon the earth, and its top reached to heaven. Behold, the angels of God ascending and descending on it.

He said to him, "Most certainly, I tell you, hereafter you will see heaven opened, and the angels of God ascending and descending on the Son of Man."

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

Jesus said to her, "Don't hold me, for I haven't yet ascended to my Father; but go to my brothers, and tell them, 'I am ascending to my Father and your Father, to my God and your God.'"
