Luke 1:21-22

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). [Note: Mishnah Yoma 5:1; ibid. Tamid 7:2.] 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.
