A short time afterward, they returned to their native country. The child had grown during those journeyings, in which his life was more than once exposed to danger. Formerly, as now, the Oriental Israelites commenced the instruction of their children at the age of five or six years. Compelled to constantly hide him from the murderous King Herod, the parents of Jesus could not allow their son to go out, and he, no doubt, spent all his time in studying the sacred Scriptures, so that his knowledge was sufficiently beyond what would naturally have been expected of a boy of his age to greatly astonish the elders of Israel. He had in his thirteenth year attained an age when, according to Jewish law, the boy becomes an adult, has the right to marry, and incurs obligations for the discharge of the religious duties of a man. There exists still, in our times, among the Israelites, an ancient religious custom that fixes the majority of a youth at the accomplished thirteenth year. From this epoch the youth becomes a member of the congregation and enjoys all the rights of an adult. Hence, his marriage at this age is regarded as having legal force, and is even required in the tropical countries. In Europe, however, owing to the influence of local laws and to nature, which does not contribute here so powerfully as in warm climates to the physical development, this custom is no more in force and has lost all its former importance. The royal lineage of Jesus, his rare intelligence and his learning, caused him to be looked upon as an excellent match, and the wealthiest and most respected Hebrews would fain have had him for a son-in-law, just as even nowadays the Israelites are very desirous of the honor of marrying their daughters to the sons of Rabbis or scholars. But the meditative youth, whose mind was far above anything corporeal, and possessed by the thirst for knowledge, stealthily left his home and joined the caravans going to India. It stands to reason that Jesus Christ should have thought, primarily, of going to India, first, because at that epoch Egypt formed part of the Roman possessions; secondly, and principally, because a very active commercial exchange with India had made common report in Judea of the majestic character and unsurpassed richness of the arts and sciences in this marvellous country, to which even now the aspirations of all civilized peoples are directed. Here the Evangelists once more lose the thread of the terrestrial life of Jesus. Luke says he "was in the deserts till the day of his shewing unto Israel" (Luke 1, 80), which clearly demonstrates that nobody knew where the holy youth was until his sudden reappearance sixteen years later. Arrived in India, this land of marvels, Jesus began to frequent the temples of the Djainites.
