At a time definitely stated as the fifteenth year of the reign of Tiberius Cæsar, emperor of Rome, the people of Judea were greatly aroused over the strange preaching of a man theretofore unknown. He was of priestly descent, but untrained in the schools; and, without authorization of the rabbis or license from the chief priests, he proclaimed himself as one sent of God with a message to Israel. He appeared not in the synagogs nor within the temple courts, where scribes and doctors taught, but cried aloud in the wilderness. The people of Jerusalem and of adjacent rural parts went out in great multitudes to hear him. He disdained the soft garments and flowing robes of comfort, and preached in his rough desert garb, consisting of a garment of camel's hair held in place by a leathern girdle. The coarseness of his attire was regarded as significant. Elijah the Tishbite, that fearless prophet whose home had been the desert, was known in his day as "an hairy man, and girt with a girdle of leather about his loins;"[273] and rough garments had come to be thought of as a distinguishing characteristic of prophets.[274] Nor did this strange preacher eat the food of luxury and ease, but fed on what the desert supplied, locusts and wild honey.[275] The man was John, son of Zacharias, soon to be known as the Baptist. He had spent many years in the desert, apart from the abodes of men, years of preparation for his particular mission. He had been a student under the tutelage of divine teachers; and there in the wilderness of Judea the word of the Lord reached him;[276] as in similar environment it had reached Moses[277] and Elijah[278] of old. Then was heard "The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight."[279] It was the voice of the herald, the messenger who, as the prophets had said, should go before the Lord to prepare His way.[280] The burden of his message was "Repent ye, for the kingdom of heaven is at hand." And to such as had faith in his words and professed repentance, confessing their sins, he administered baptism by immersion in water--proclaiming the while, "I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire."[281]
