Luke 1:5-7

5 THERE was in the days of Herod, the king of Judaea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth.

6 And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

7 And they had no child, because that Elisabeth was barren, and they both were now well stricken in years.
