Luke 1:3-7 KJV

3 It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus, 4 That thou mightest know the certainty of those things, wherein thou hast been instructed. 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.
