Luke 1:11-13

11 And an angel of the Lord appeared to him, and stood on the right half of the altar of incense.

12 And Zechariah seeing was afraid [or distroubled], and dread fell upon him.

13 And the angel said to him, Zechariah, dread thou not; for thy prayer is heard, and Elisabeth, thy wife, shall bear to thee a son, and his name shall be called John.
