"Such was the work that went on day by day throughout the year. The sins of Israel being thus transferred to the sanctuary, the holy places were defiled, and a special work became necessary for the removal of the sins. God commanded that an atonement be made for each of the sacred apartments, as for the altar, to “cleanse it, and hallow it from the uncleanness of the children of Israel.” Leviticus 16:19 . PP 355.1"
"And he shall sprinkle of the blood upon it with his finger seven times, and cleanse it, and hallow it from the uncleanness of the children of Israel."
Ellen White directly references Leviticus 16:19 in this passage.
"Once a year, on the great Day of Atonement, the priest entered the most holy place for the cleansing of the sanctuary. The work there performed completed the yearly round of ministration. PP 355.2"
"And this shall be an everlasting statute unto you, to make an atonement for the children of Israel for all their sins once a year. And he did as the Lord commanded Moses."
The EGW passage directly describes the event mandated in Leviticus 16:34, the Day of Atonement. It's more than just an allusion; it's a description of the practice itself.
"“And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness: and the goat shall bear upon him all their iniquities into a land not inhabited.” Not until the goat had been thus sent away did the people regard themselves as freed from the burden of their sins. Every man was to afflict his soul while the work of atonement was going forward. All business was laid aside, and the whole congregation of Israel spent the day in solemn humiliation before God, with prayer, fasting, and deep searching of heart. PP 355.4"
"And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:"
EGW directly quotes Leviticus 16:21 and elaborates on the ritual of the scapegoat, making a clear and direct connection.
Important truths concerning the atonement were taught the people by this yearly service. In the sin offerings presented during the year, a substitute had been accepted in the sinner's stead; but the blood of the victim had not made full atonement for the sin. It had only provided a means by which the sin was transferred to the sanctuary. By the offering of blood, the sinner acknowledged the authority of the law, confessed the guilt of his transgression, and expressed his faith in Him who was to take away the sin of the world; but he was not entirely released from the condemnation of the law. On the Day of Atonement the high priest, having taken an offering for the congregation, went into the most holy place with the blood and sprinkled it upon the mercy seat, above the tables of the law. Thus the claims of the law, which demanded the life of the sinner, were satisfied. Then in his character of mediator the priest took the sins upon himself, and, leaving the sanctuary, he bore with him …
"Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount."
Ellen White directly references Hebrews 8:5 in this passage.
"For it is not possible that the blood of bulls and of goats should take away sins."
EGW's statement directly explains the limitations of the animal sacrifices, which Hebrews 10:4 also emphasizes. The EGW passage amplifies the meaning and purpose of the sacrifices in relation to the ultimate atonement.
