according to the custom of the priest's office, his lot was to enter into the temple of the Lord and burn incense.
"There were four lots there, and this was the first lot (i.e. to cleanse the altar); the second lot was, who should slay (the sacrifice,) who should sprinkle (the blood), who should remove the ashes from the innermost altar, who should cleanse the candlestick, who should bring the members (or parts of the sacrifice) to the ascent of the altar----the third lot was, ye new ones, to the incense come, והפיסו, and "cast lots"; and the fourth, ye new ones, with the old ones, who shall bring up the parts from the ascent of the altar to the altar.''
