Luke 1:5-7

The Birth of John the Baptist Foretold 5In 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. 6Both of them were righteous in the sight of God, observing all the Lord’s commands and decrees blamelessly.

7But they were childless because Elizabeth was not able to conceive, and they were both very old.
