Luke 1:8-11

One day Zechariah was serving God in the Temple, for his order was on duty that week. As was the custom of the priests, he was chosen by lot to enter the sanctuary of the Lord and burn incense. While the incense was being burned, a great crowd stood outside, praying. While Zechariah was in the sanctuary, an angel of the Lord appeared to him, standing to the right of the incense altar.
