"In distress Moses cried to the Lord, “What shall I do unto this people?” He was directed to take the elders of Israel and the rod wherewith he had wrought wonders in Egypt, and to go on before the people. And the Lord said unto him, “Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink.” He obeyed, and the waters burst forth in a living stream that abundantly supplied the encampment. Instead of commanding Moses to lift up his rod and call down some terrible plague, like those on Egypt, upon the leaders in this wicked murmuring, the Lord in His great mercy made the rod His instrument to work their deliverance. PP 298.1"
"And the Lord said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go. Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel."
EGW directly quotes Exodus 17:5-6.
"flow. Not only Moses and the elders, but all the congregation who stood at a distance, beheld the glory of the Lord; but had the cloud been removed, they would have been slain by the terrible brightness of Him who abode therein. PP 298.2"
"And he said, Thou canst not see my face: for there shall no man see me, and live."
The EGW passage directly references the idea that seeing God's glory would be fatal, which is the core concept of Exodus 33:20.
"In their thirst the people had tempted God, saying, “Is the Lord among us, or not?”—“If God has brought us here, why does He not give us water as well as bread?” The unbelief thus manifested was criminal, and Moses feared that the judgments of God would rest upon them. And he called the name of the place Massah, “temptation,” and Meribah, “chiding,” as a memorial of their sin. PP 298.3"
"And he called the name of the place Massah, and Meribah, because of the chiding of the children of Israel, and because they tempted the Lord, saying, Is the Lord among us, or not?"
The EGW passage directly quotes and explains the naming of Massah and Meribah as described in Exodus 17:7, linking it to the Israelites' temptation of God.
A new danger now threatened them. Because of their murmuring against Him, the Lord suffered them to be attacked by their enemies. The Amalekites, a fierce, warlike tribe inhabiting that region, came out against them and smote those who, faint and weary, had fallen into the rear. Moses, knowing that the masses of the people were unprepared for battle, directed Joshua to choose from the different tribes a body of soldiers, and lead them on the morrow against the enemy, while he himself would stand on an eminence near by with the rod of God in his hand. Accordingly the next day Joshua and his company attacked the foe, while Moses and Aaron and Hur were stationed on a hill overlooking the battlefield. With arms outstretched toward heaven, and holding the rod of God in his right hand, Moses prayed for the success of the armies of Israel. As the battle progressed, it was observed that so long as his hands were reaching upward, Israel prevailed, but when they were lowered, the enemy was victo…
"Then came Amalek, and fought with Israel in Rephidim. And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand."
The EGW passage closely follows the narrative of Exodus 17:8-9, detailing the attack by the Amalekites, Moses' instructions to Joshua, and his position on the hill with the rod of God.
