The ministration of the earthly sanctuary consisted of two divisions; the priests ministered daily in the holy place, while once a year the high priest performed a special work of atonement in the most holy, for the cleansing of the sanctuary. Day by day the repentant sinner brought his offering to the door of the tabernacle and, placing his hand upon the victim's head, confessed his sins, thus in figure transferring them from himself to the innocent sacrifice. The animal was then slain. “Without shedding of blood,” says the apostle, there is no remission of sin. “The life of the flesh is in the blood.” Leviticus 17:11 . The broken law of God demanded the life of the transgressor. The blood, representing the forfeited life of the sinner, whose guilt the victim bore, was carried by the priest into the holy place and sprinkled before the veil, behind which was the ark containing the law that the sinner had transgressed.

"For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul."

"Wherefore have ye not eaten the sin offering in the holy place, seeing it is most holy, and God hath given it you to bear the iniquity of the congregation, to make atonement for them before the Lord?"
Ellen White directly references Leviticus 10:17 in this passage.
"Such was the work that went on, day by day, throughout the year. The sins of Israel were thus transferred to the sanctuary, and a special work became necessary for their removal. God commanded that an atonement be made for each of the sacred apartments. “He shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.” An atonement was also to be made for the altar, to “cleanse it, and hallow it from the uncleanness of the children of Israel.” Leviticus 16:16, 19 . GC 418.2"
"And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness."
EGW directly quotes Leviticus 16:16 to explain the atonement made for the holy place due to the uncleanness of the children of Israel. This is a clear and direct reference.
