'Descending' in the Bible

John testified saying, “I have seen the Spirit descending as a dove out of heaven, and He remained upon Him.

I did not recognize Him, but He who sent me to baptize in water said to me, ‘He upon whom you see the Spirit descending and remaining upon Him, this is the One who baptizes in the Holy Spirit.’

And He *said to him, “Truly, truly, I say to you, you will see the heavens opened and the angels of God ascending and descending on the Son of Man.”
