Luke 1:5-25

There was in the days of Herod, the king of Judea, a certain priest named Zacharias, of the division of Abijah. His wife was of the daughters of Aaron, and her name was Elizabeth.
6 And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

7 But they had no child, because Elizabeth was barren, and they were both well advanced in years.

8 So it was, that while he was serving as priest before God in the order of his division, 9 according to the custom of the priesthood, his lot fell to burn incense when he went into the temple of the Lord. 10 And the whole multitude of the people was praying outside at the hour of incense.

11 Then an angel of the Lord appeared to him, standing on the right side of the altar of incense.

What was Zacharias Thinking? –

12 And when Zacharias saw him, he was troubled, and fear fell upon him.

13 But the angel said to him, “Do not be afraid, Zacharias, for your prayer is heard; and your wife Elizabeth will bear you a son, and you shall call his name John. 14 “And you will have joy and gladness, and many will rejoice at his birth.

….

18 And Zacharias said to the angel, “How shall I know this? For I am an old man, and my wife is well advanced in years.”

19 And the angel answered and said to him, “I am Gabriel, who stands in the presence of God, and was sent to speak to you and bring you these glad tidings.

….

24 Now after those days his wife Elizabeth conceived; and she hid herself five months, saying,
25 “Thus the Lord has dealt with me, in the days when He looked on me, to take away my reproach among people.”
