Barnes' Notes
For he received from God the Father honour and glory - He was honored by God in being thus addressed.
When there came such a voice to him from the excellent glory - The magnificent splendor; the bright cloud which overshadowed them, Matthew 17:5.
This is my beloved Son, in whom I am well pleased - See the notes at Matthew 17:5; Matthew 3:17. This demonstrated that he was the Messiah. Those who heard that voice could not doubt this; they never did afterwards doubt.
