Luke 1:3-7

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,

That thou mightest know the certainty of those things, wherein thou hast been instructed.

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

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

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