Because they had been shielded by divine power they had not realized the countless dangers by which they were continually surrounded. In their ingratitude and unbelief they had anticipated death, and now the Lord permitted death to come upon them. The poisonous serpents that infested the wilderness were called fiery serpents, on account of the terrible effects produced by their sting, it causing violent inflammation and speedy death. As the protecting hand of God was removed from Israel, great numbers of the people were attacked by these venomous creatures. (PP 429.1) MC VC

Now there was terror and confusion throughout the encampment. In almost every tent were the dying or the dead. None were secure. Often the silence of night was broken by piercing cries that told of fresh victims. All were busy in ministering to the sufferers, or with agonizing care endeavoring to protect those who were not yet stricken. No murmuring now escaped their lips. When compared with the present suffering, their former difficulties and trials seemed unworthy of a thought. (PP 429.2) MC VC

The people now humbled themselves before God. They came to Moses with their confessions and entreaties. “We have sinned,” they said, “for we have spoken against the Lord, and against thee.” Numbers 21:7. Only a little before, they had accused him of being their worst enemy, the cause of all their distress and afflictions. But even when the words were upon their lips, they knew that the charge was false; and as soon as real trouble came they fled to him as the only one who could intercede with God for them. “Pray unto the Lord,” was their cry, “that He take away the serpents from us.” Numbers 21:7.
