Luke 1:4 WEB

⁴  that you might know the certainty concerning the things in which you were instructed.

⁵  There was in the days of Herod, the king of Judea, a certain priest named Zacharias, of the priestly division of Abijah. He had a wife of the daughters of Aaron, and her name was Elizabeth.

⁶  They were both righteous before God, walking blamelessly in all the commandments and ordinances of the Lord.
