Luke 1:9

His lot— Because some parts of the sacred service were more honourable than others, both the priests and Levites divided the whole among them by lot. The Jews tell us, that there were three priests employed about the service of the incense; one carried away the ashes left on the altar at the preceding service; another brought a pan of burning coals from the altar of sacrifice, and, having placed it on the golden altar, departed; a thirdwent in with the incense, sprinkled it on the burning coals, and, while the smoke ascended, made intercession for the people. This was the part that fell to Zacharias, and the most honourable in the whole service. Dr. Heylin renders this verse, According to the custom of distributing the sacerdotal functions, the lot fell upon him to enter into the sanctuary, and offer incense.
