Moses and “his minister Joshua”(Exodus 24:13) were now summoned to meet with God. And as they were to be some time absent, the leader appointed Aaron and Hur, assisted by the elders, to act in his stead. “And Moses went up into the mount, and a cloud covered the mount. And the glory of the Lord abode upon Mount Sinai.” Exodus 24:15, 16. For six days the cloud covered the mountain as a token of God’s special presence; yet there was no revelation of Himself or communication of His will. During this time Moses remained in waiting for a summons to the presence chamber of the Most High. He had been directed, “Come up to Me into the mount, and be there,”(Exodus 24:12) and though his patience and obedience were tested, he did not grow weary of watching, or forsake his post. This period of waiting was to him a time of preparation, of close self-examination. Even this favored servant of God could not at once approach into His presence and endure the exhibitions of His glory. Six days must be employed in devoting himself to God by searching of heart, meditation, and prayer before he could be prepared for direct communication with his Maker. (PP 313.1) MC VC

Upon the seventh day, which was the Sabbath, Moses was called up into the cloud. The thick cloud opened in the sight of all Israel, and the glory of the Lord broke forth like devouring fire. “And Moses went into the midst of the cloud, and gat him up into the mount; and Moses was in the mount forty days and forty nights.” Exodus 24:18. The forty days’ tarry in the mount did not include the six days of preparation. During the six days Joshua was with Moses, and together they ate of the manna and drank of “the brook that descended out of the mount.” But Joshua did not enter with Moses into the cloud. He remained without, and continued to eat and drink daily while awaiting the return of Moses, but Moses fasted during the entire forty days. (PP 313.2) MC VC

During his stay in the mount, Moses received directions for the building of a sanctuary in which the divine presence would be specially manifested. “Let them make Me a sanctuary; that I may dwell among them” (Exodus 25:8), was the command of God. For the third time the observance of the Sabbath was enjoined. “It is a sign between Me and the children of Israel forever,” the Lord declared, “that ye may know that I am Jehovah that doth sanctify you. Ye shall keep the Sabbath therefore; for it is holy unto you.... Whosoever doeth any work therein, that soul shall be cut off from among his people.” Exodus 31:17, 13, 14. Directions had just been given for the immediate erection of the tabernacle for the service of God; and now the people might conclude, because the object had in view was the glory of God, and also because of their great need of a place of worship, that they would be justified in working at the building upon the Sabbath. To guard them from this error, the warning was given. Even the sacredness and urgency of that special work for God must not lead them to infringe upon His holy rest day. (PP 313.3) MC VC

Henceforth the people were to be honored with the abiding presence of their King. “I will dwell among the children of Israel, and will be their God,” “and the tabernacle shall be sanctified by My glory” (Exodus 29:45, 43), was the assurance given to Moses. As the symbol of God’s authority and the embodiment of His will, there was delivered to Moses a copy of the Decalogue engraved by the finger of God Himself upon two tables of stone (Deuteronomy 9:10; Exodus 32:15, 16), to be sacredly enshrined in the sanctuary, which, when made, was to be the visible center of the nation’s worship. (PP 314.1) MC VC

From a race of slaves the Israelites had been exalted above all peoples to be the peculiar treasure of the King of kings. God had separated them from the world, that He might commit to them a sacred trust. He had made them the depositaries of His law, and He purposed, through them, to preserve among men the knowledge of Himself. Thus the light of heaven was to shine out to a world enshrouded in darkness, and a voice was to be heard appealing to all peoples to turn from their idolatry to serve the living God. If the Israelites would be true to their trust, they would become a power in the world. God would be their defense, and He would exalt them above all other nations. His light and truth would be revealed through them, and they would stand forth under His wise and holy rule as an example of the superiority of His worship over every form of idolatry. (PP 314.2) MC VC

He did not even then trust His precepts to the memory of a people who were prone to forget His requirements, but wrote them upon tables of stone. He would remove from Israel all possibility of mingling heathen traditions with His holy precepts, or of confounding His requirements with human ordinances or customs. But He did not stop with giving them the precepts of the Decalogue. The people had shown themselves so easily led astray that He would leave no door of temptation unguarded. Moses was commanded to write, as God should bid him, judgments and laws giving minute instruction as to what was required. These directions relating to the duty of the people to God, to one another, and to the stranger were only the principles of the Ten Commandments amplified and given in a specific manner, that none need err. They were designed to guard the sacredness of the ten precepts engraved on the tables of stone. (PP 364.1) MC VC

If man had kept the law of God, as given to Adam after his fall, preserved by Noah, and observed by Abraham, there would have been no necessity for the ordinance of circumcision. And if the descendants of Abraham had kept the covenant, of which circumcision was a sign, they would never have been seduced into idolatry, nor would it have been necessary for them to suffer a life of bondage in Egypt; they would have kept God’s law in mind, and there would have been no necessity for it to be proclaimed from Sinai or engraved upon the tables of stone. And had the people practiced the principles of the Ten Commandments, there would have been no need of the additional directions given to Moses. (PP 364.2) MC VC

The sacrificial system, committed to Adam, was also perverted by his descendants. Superstition, idolatry, cruelty, and licentiousness corrupted the simple and significant service that God had appointed. Through long intercourse with idolaters the people of Israel had mingled many heathen customs with their worship; therefore the Lord gave them at Sinai definite instruction concerning the sacrificial service. After the completion of the tabernacle He communicated with Moses from the cloud of glory above the mercy seat, and gave him full directions concerning the system of offerings and the forms of worship to be maintained in the sanctuary. The ceremonial law was thus given to Moses, and by him written in a book. But the law of Ten Commandments spoken from Sinai had been written by God Himself on the tables of stone, and was sacredly preserved in the ark. (PP 364.3) MC VC
