It was not unknown for a priest to see a vision or hear a heavenly voice in the sanctuary at the time of the incense offering. Josephus relates that while the high priest and ruler John Hyrcanus was offering incense in the sanctuary, he heard a voice proclaiming that his sons had just defeated the Syrian king Antiochus (Antiq. 13:282).
According to the gospel of Luke, Zechariah’s wife Elizabeth was of the “daughters of Aaron,” that is the daughter of a priest. It was common in that period to refer to people of priestly stock as descendants of Aaron. For example, a first-century inscription found in Jerusalem in 1971 mentions the heroic exploits of a person who introduces himself as: “I Abba son of the priest Eleaz[ar] the son of the great Aaron.”
