Luke 1:10 ASV

⁸  Now it came to pass, while he executed the priest's office before God in the order of his course,

⁹  according to the custom of the priest's office, his lot was to enter into the temple of the Lord and burn incense.

¹⁰  And the whole multitude of the people were praying without at the hour of incense.

¹¹  And there appeared unto him an angel of the Lord standing on the right side of altar of incense.

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