Luke 1:9

⁷  And they had no child, because that Elisabeth was barren, and they both were now well stricken in years.

⁸  And it came to pass, that 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 burn incense when he went into the temple of the Lord.

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

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