Barnes' Notes
The people - A part of the people.
It thundered - The unexpected sound of the voice would confound and amaze them; and though there is no reason to doubt that the words were spoken distinctly Matthew 3:17, yet some of the people, either from amazement or envy, would suppose that this was a mere natural phenomenon.
An angel spake - It was the opinion of many of the Jews that God did not speak to men except by the ministry of angels, Hebrews 2:2; "The word spoken by angels;" Galatians 3:19; "It was ordained by angels in the hand of a mediator."
