Luke 1:4 KJV

2Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word;

3It 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,

4That thou mightest know the certainty of those things, wherein thou hast been instructed.

5There 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.

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