Luke 1:10 WBT

⁸  And it came to pass, that, while he executed the priests' office before God in the order of his course,

⁹  According to the custom of the priests' 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 to him an angel of the Lord, standing on the right side of the altar of incense.

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