Luke 1:5-7

5There was in the days of Herod, the king of Judea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth. 6And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. 7And they had no child, because that Elisabeth was barren, and they both were now well stricken in years.
