Hardly had they departed from Sinai when they once more began to lead the wicked course of life that they had for a time abandoned. They began to seek a pretext to renounce God and again to be addicted to idolatry. They complained about the forced marches which at God's command they had been obliged to make after their departure from Sinai, and in this way showed their ingratitude to God who wanted them as quickly as possible to reach the Holy Land, and for this reason allowed them to cover an eleven days' distance in three days. Their murmurs and complaints, however, were not silent, but quite loud, for they were anxious that God should hear their wicked words. In punishment for their defamation of the Divine glory, God sent upon them a fire emanating from the very glory.
