Luke 1:11

‘And there appeared to him an angel of the Lord standing on the right side of altar of incense.'

And then suddenly, alone in the semi-darkness, there in that outer sanctuary lit only by the seven-branched lampstand, Zacharias received a terrible shock. For it was obligatory for the sanctuary to be empty at the time of the offering of the incense, and yet in the dim light he became aware of a figure, standing to the right of the golden altar of incense, the side of privilege. And he was not dressed as a priest. There was an intruder in the sanctuary.
