Luke 1:9

Lot] To avoid disputes the various functions were decided by lot. To burn incense] This was done daily, morning and evening (Exodus 30:6). The daily sacrifice of the lamb was offered on the great altar of burnt offering outside the Temple proper, in front of the porch. The incense was offered inside the Temple on the golden altar of incense which stood before the veil of the Holy of Holies. The officiating priest was alone within the Temple while offering the incense, and the other priests and the people were outside worshipping in the various Temple courts. Only once in a. lifetime could a man enjoy this privilege, and he was ever afterwards called 'rich.' It was the 'highest, mediatorial act,' 'the most solemn part of the day's service, symbolising Israel's accepted prayers.'
