Zechariah"s delay in the temple and then his inability to speak impressed the worshippers that something supernatural had occurred. Normally he would have pronounced the Aaronic blessing over them ( Numbers 6:24-26). [1] The people assumed incorrectly that he had seen a vision. Zechariah was unable to communicate to them what had really happened. Luke recorded their reaction to impress his readers with the importance of this event. [source][source][source]
