Many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. Therefore, since I myself have carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught. In the time of Herod king of Judea there was a priest named Zechariah, who belonged to the priestly division of Abijah, his wife Elizabeth was also a descendant of Aaron. Both of them were upright in the sight of God, observing all the Lord's commandments and regulations blamelessly. But they had no children, because Elizabeth was barren, and they were both well along in years.
