As they continued their journey toward the south, their route lay through a hot, sandy valley, destitute of shade or vegetation. The way seemed long and difficult, and they suffered from weariness and thirst. Again they failed to endure the test of their faith and patience. By continually dwelling on the dark side of their experiences, they separated themselves farther and farther from God. They lost sight of the fact that but for their murmuring when the water ceased at Kadesh, they would have been spared the journey around Edom. God had purposed better things for them. Their hearts should have been filled with gratitude to Him that He had punished their sin so lightly. But instead of this, they flattered themselves that if God and Moses had not interfered, they might now have been in possession of the Promised Land. After bringing trouble upon themselves, making their lot altogether harder than God designed, they charged all their misfortunes upon Him. Thus they cherished bitter thou…
"And they journeyed from mount Hor by the way of the Red sea, to compass the land of Edom: and the soul of the people was much discouraged because of the way."
Both passages describe the Israelites' journey around Edom, their discouragement, and their murmuring due to the difficult conditions. EGW expands on the reasons for their discontent, but the core theme of hardship and complaint is present in both.
"As the Israelites indulged the spirit of discontent, they were disposed to find fault even with their blessings. “And the people spake against God, and against Moses, Wherefore have ye brought us up out of Egypt to die in the wilderness? for there is no bread, neither is there any water; and our soul loatheth this light bread.” PP 428.2"
"And the people spake against God, and against Moses, Wherefore have ye brought us up out of Egypt to die in the wilderness? for there is no bread, neither is there any water; and our soul loatheth this light bread."
The EGW passage directly quotes Numbers 21:5.
Moses faithfully set before the people their great sin. It was God's power alone that had preserved them in “that great and terrible wilderness, wherein were fiery serpents, and scorpions, and drought, where there was no water.” Deuteronomy 8:15 . Every day of their travels they had been kept by a miracle of divine mercy. In all the way of God's leading they had found water to refresh the thirsty, bread from heaven to satisfy their hunger, and peace and safety under the shadowy cloud by day and the pillar of fire by night. Angels had ministered to them as they climbed the rocky heights or threaded the rugged paths of the wilderness. Notwithstanding the hardships they had endured, there was not a feeble one in all their ranks. Their feet had not swollen in their long journeys, neither had their clothes grown old. God had subdued before them the fierce beasts of prey and the venomous reptiles of the forest and the desert. If with all these tokens of His love the people still continued to…
"Who led thee through that great and terrible wilderness, wherein were fiery serpents, and scorpions, and drought, where there was no water; who brought thee forth water out of the rock of flint;"
