Luke 1:8-11

One day, Zechariah’s priestly order was on duty and he was serving as priest. He was chosen by the casting of lots (according to the custom of the priesthood) so the honor fell upon Zechariah to enter the Holy Place and burn incense before the Lord. A large crowd of worshipers had gathered to pray outside the temple at the hour when incense was being offered. All at once an angel of the Lord appeared to him, standing just to the right of the altar of incense.
