"They were unwilling to submit to the terrible sentence that they must all die in the wilderness, and hence they were ready to seize upon every pretext for believing that it was not God but Moses who was leading them and who had pronounced their doom. The best efforts of the meekest man upon the earth could not quell the insubordination of this people; and although the marks of God's displeasure at their former perverseness were still before them in their broken ranks and missing numbers, they did not take the lesson to heart. Again they were overcome by temptation. PP 396.1"
"And all the children of Israel murmured against Moses and against Aaron: and the whole congregation said unto them, Would God that we had died in the land of Egypt! or would God we had died in this wilderness!"
Both passages highlight the Israelites' discontent with their situation and their resentment towards Moses' leadership, specifically their desire to have died in Egypt or the wilderness rather than face their current circumstances.
"The humble shepherd's life of Moses had been far more peaceful and happy than his present position as leader of that vast assembly of turbulent spirits. Yet Moses dared not choose. In place of a shepherd's crook a rod of power had been given him, which he could not lay down until God should release him. PP 396.2"
"Now Moses kept the flock of Jethro his father in law, the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb."
Both passages refer to Moses' earlier life as a shepherd. The EGW passage contrasts this peaceful existence with the challenges of leading the Israelites, while Exodus 3:1 simply establishes his background.
"He who reads the secrets of all hearts had marked the purposes of Korah and his companions and had given His people such warning and instruction as might have enabled them to escape the deception of these designing men. They had seen the judgment of God fall upon Miriam because of her jealousy and complaints against Moses. The Lord had declared that Moses was greater than a prophet. “With him will I speak mouth to mouth.” “Wherefore, then,” He added, “were ye not afraid to speak against My servant Moses?” Numbers 12:8 . These instructions were not intended for Aaron and Miriam alone, but for all Israel. PP 396.3"
"With him will I speak mouth to mouth, even apparently, and not in dark speeches; and the similitude of the Lord shall he behold: wherefore then were ye not afraid to speak against my servant Moses?"
Ellen White directly references Numbers 12:8 in this passage.
"Korah and his fellow conspirators were men who had been favored with special manifestations of God's power and greatness. They were of the number who went up with Moses into the mount and beheld the divine glory. But since that time a change had come. A temptation, slight at first, had been harbored, and had strengthened as it was encouraged, until their minds were controlled by Satan, and they ventured upon their work of disaffection. Professing great interest in the prosperity of the people, they first whispered their discontent to one another and then to leading men of Israel. Their insinuations were so readily received that they ventured still further, and at last they really believed themselves to be actuated by zeal for God. PP 396.4"
"And they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the assembly, famous in the congregation, men of renown:"
The EGW passage directly refers to Korah's rebellion and mentions the 'men of renown' who joined him. This is a clear and direct reference to Numbers 16:2, which identifies these individuals. The EGW passage amplifies the biblical account by providing further details about their motivations and influence.
