11 “When Aaron presents the bull for his sin offering and makes atonement for himself and his household, he will slaughter the bull for his sin offering. 12 Then he is to take a firepan full of blazing coals from the altar before the Lord and two handfuls of finely ground fragrant incense,d and bring them inside the curtain.e 13 He is to put the incense on the fire before the Lord, so that the cloudf of incense covers the mercy seat that is over the testimony,g or else he will die.h 14 He is to take some of the bull’s bloodi and sprinkle it with his finger against the east side of the mercy seat; then he will sprinkle some of the blood with his finger before the mercy seat seven times.j
