Catena Aurea · Lukasevangelium 1
And it came to pass, that while he executed the Priest’s office before God in the order of his course, According to the custom of the Priest’s office, his lot was to burn incense when he went into the temple of the Lord. And the whole multitude of the people were praying without at the time of incense.
Zacharias seems here to be designated High Priest, because into the second tabernacle went the High Priest alone once every year, not without blood, which he offered for himself and the sins of the people. (Heb. 9:7.)
