'Descending' in the Bible

And John testified, saying, "I have seen the Spirit descending like a dove from heaven and remaining upon him.

And I did not know him, but the one who sent me to baptize with water, that one said to me, '[The one] upon whom you see the Spirit descending and remaining upon him--this one is the one who baptizes with the Holy Spirit.'

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."
