according to the custom of the priest's office, his lot was to enter into the temple of the Lord and burn incense.
"he that is worthy of the incense, takes the bowl out of the vessel, and gives it to his friend, or he that is near to him; and if it is scattered from it, in the midst of it, he puts it into his fist; and they teach him, "saying", take care that thou dost not begin before thy face, that thou art not burnt: when he begins, he spreads it and goes out; and he that burns incense, may not do it, until the president says, burn incense.''
