"The spot chosen was one of the most beautiful in all Palestine, and worthy to be the theater where this grand and impressive scene was to be enacted. The lovely valley, its green fields dotted with olive groves, watered with brooks from living fountains, and gemmed with wild flowers, spread out invitingly between the barren hills. Ebal and Gerizim, upon opposite sides of the valley, nearly approach each other, their lower spurs seeming to form a natural pulpit, every word spoken on one being distinctly audible on the other, while the mountainsides, receding, afford space for a vast assemblage. PP 500.1"
"And it shall come to pass, when the Lord thy God hath brought thee in unto the land whither thou goest to possess it, that thou shalt put the blessing upon mount Gerizim, and the curse upon mount Ebal."
The EGW passage describes the setting of the blessing and curse ceremony on Mount Gerizim and Ebal, which is directly related to the command in Deuteronomy 11:29. While the EGW passage provides a more detailed description of the location, the connection to the biblical text is clear and meaningful.
"According to the directions given by Moses, a monument of great stones was erected upon Mount Ebal. Upon these stones, previously prepared by a covering of plaster, the law was inscribed—not only the ten precepts spoken from Sinai and engraved on the tables of stone, but the laws communicated to Moses, and by him written in a book. Beside this monument was built an altar of unhewn stone, upon which sacrifices were offered unto the Lord. The fact that the altar was set up on Mount Ebal, the mountain upon which the curse was put, was significant, denoting that because of their transgressions of God's law, Israel had justly incurred His wrath, and that it would be at once visited, but for the atonement of Christ, represented by the altar of sacrifice. PP 500.2"
"And it shall be on the day when ye shall pass over Jordan unto the land which the Lord thy God giveth thee, that thou shalt set thee up great stones, and plaister them with plaister:"
Both passages refer to setting up great stones and plastering them, as commanded in Deuteronomy.
"And there shalt thou build an altar unto the Lord thy God, an altar of stones: thou shalt not lift up any iron tool upon them."
Both passages refer to building an altar of unhewn stones.
"Six of the tribes—all descended from Leah and Rachel—were stationed upon Mount Gerizim; while those that descended from the handmaids, together with Reuben and Zebulun, took their position on Ebal, the priests with the ark occupying the valley between them. Silence was proclaimed by the sound of the signal trumpet; and then in the deep stillness, and in the presence of this vast assembly, Joshua, standing beside the sacred ark, read the blessings that were to follow obedience to God's law. All the tribes on Gerizim responded by an Amen. He then read the curses, and the tribes on Ebal in like manner gave their assent, thousands upon thousands of voices uniting as the voice of one man in the solemn response. Following this came the reading of the law of God, together with the statutes and judgments that had been delivered to them by Moses. PP 500.3"
"These shall stand upon mount Gerizim to bless the people, when ye are come over Jordan; Simeon, and Levi, and Judah, and Issachar, and Joseph, and Benjamin:"
Both passages refer to the tribes standing on Mount Gerizim to bless.
"And these shall stand upon mount Ebal to curse; Reuben, Gad, and Asher, and Zebulun, Dan, and Naphtali."
Both passages refer to the tribes standing on Mount Ebal to curse.
"Israel had received the law directly from the mouth of God at Sinai; and its sacred precepts, written by His own hand, were still preserved in the ark. Now it had been again written where all could read it. All had the privilege of seeing for themselves the conditions of the covenant under which they were to hold possession of Canaan. All were to signify their acceptance of the terms of the covenant and give their assent to the blessings or curses for its observance or neglect. The law was not only written upon the memorial stones, but was read by Joshua himself in the hearing of all Israel. It had not been many weeks since Moses gave the whole book of Deuteronomy in discourses to the people, yet now Joshua read the law again. PP 500.4"
"And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God."
The EGW passage directly references the law being written by God's own hand on tables of stone, which is a clear allusion to Exodus 31:18. The context of the law's importance and its origin is shared between the two passages.
