His lot was to burn incense; more accurately, he obtained by lot the duty of entering and offering incense. The office of burning incense gave the priest to whom this important lot fell the right of entering the holy place.
It was the most coveted of all the priestly duties. The Talmud says the priest who obtained the right to perform this high duty was not permitted to draw the lot a second time in the same week, and as the whole number of priests at this time was very large—some say even as many as twenty thousand—Farrar conjectures that it would never happen to the same priest twice in his lifetime to enter that sacred spot.
