"When God called for Moses to come up into the mount, it was six days before he was received into the cloud, into the immediate presence of God. The top of the mountain was all aglow with the glory of God. And yet even while the children of Israel had this glory in their very sight, unbelief was so natural to them that they began to murmur with discontent because Moses was absent. While the glory of God signified His sacred presence upon the mountain, and their leader was in close converse with God, they should have been sanctifying themselves by close searching of heart, humiliation, and godly fear. God had left Aaron and Hur to take the place of Moses. In his absence the people were to consult and advise with these men of God's appointment. 3T 296.1"
"And Moses went up into the mount, and a cloud covered the mount. And the glory of the Lord abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud. And the sight of the glory of the Lord was like devouring fire on the top of the mount in the eyes of the children of Israel. 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."
The EGW passage directly references the events of Moses going up Mount Sinai, the glory of God appearing as fire, and the people's murmuring during his absence, all described in Exodus 24:15-18.
"Here Aaron's deficiency as a leader or governor of Israel is seen. The people beset him to make them gods to go before them into Egypt. Here was an opportunity for Aaron to show his faith and unwavering confidence in God, and with firmness and decision to meet the proposition of the people. But his natural desire to please and to yield to the people led him to sacrifice the honor of God. He requested them to bring their ornaments to him, and he wrought out for them a golden calf and proclaimed before the people: “These be thy gods, O Israel, which brought thee up out of the land of Egypt.” And to this senseless god he made an altar and proclaimed on the morrow a feast to the Lord. All restraint seemed to be removed from the people. They offered burnt offerings to the golden calf, and a spirit of levity took possession of them. They indulged in shameful rioting and drunkenness; they ate, they drank, and rose up to play. 3T 296.2"
"And when the people saw that Moses delayed to come down out of the mount, the people gathered themselves together unto Aaron, and said unto him, Up, make us gods, which shall go before us; for as for this Moses, the man that brought us up out of the land of Egypt, we wot not what is become of him."
The EGW passage directly recounts the events of the Israelites asking Aaron to make them gods, Aaron creating the golden calf, and the subsequent idolatry and revelry, as described in Exodus 32:1 and following verses.
