8Now it happened that while he was performing his priestly service before God in the appointed order of his division, 9according to the custom of the priestly office, he was chosen by lot to enter the temple of the Lord and burn incense. 10And the whole multitude of the people were in prayer outside at the hour of the incense offering. 11Now an angel of the Lord appeared to him, standing to the right of the altar of incense. 12Zechariah was troubled when he saw the angel, and fear gripped him.
