There are three different modes by which we proceed towards the most excellent end, namely, instruction, nature, and practise. There are also three persons, the oldest of the wise men who in the account given to us by Moses derive three names from these modes, whose lives I have now discussed, having examined the man who arrived at excellence in consequence of instruction, and him who was self-taught, and him who attained to the proposed end by practise. Accordingly, proceeding in regular order, I will now describe the life of the man occupied in civil affairs. And again, Moses has given us one of the patriarchs as deriving his name from this kind of life, in which he had been immersed from his earliest youth.
 Now, this man began from the time he was seventeen years of age to be occupied with the consideration of the business of a shepherd, which corresponds to political business. On which account I think it is that the race of poets has been accustomed to call kings the shepherds of the people; for he who is skilful in the business of a shepherd will probably be also a most excellent king, having derived instruction in those matters which are deserving of inferior attention here to superintend a flock of those most excellent of all animals, namely, of men. And just as attention to matters of hunting is indispensable to the man who is about to conduct a war or to govern an army, so in the same manner those who hope to have the government of a city will find the business of a shepherd very closely connected with them, since that is as it were a sort of prelude to any kind of government. Therefore, as this man’s father perceived in his son a very noble ability, and too great to be left in the obscurity of a private station, he admired him, and cultivated his talent, and loved him more than his other sons; because, too, he was the son of his old age, which last cause is one of the strongest incentives to affection possible.
 
And like a man fond of virtue, he cherished and kindled the natural good disposition of his son by excessive and most diligent care and attention, in order that it might not only not be smothered, but might shine forth more brilliantly.
 But envy is at all times an adversary to great good fortune, and at this time it attacked a house which was prospering in all its parts, and divided it, setting all the brothers in enmity against one, who displayed an ill feeling on their own parts, sufficient to counterbalance the affection of his father, hating their brother as much as their father loved him; but they did not divulge their hatred by words, but kept it in their own bosoms, on which account it very naturally became more grievous and bitter; for passions which are repressed, and which are not allowed to evaporate in language, are more difficult to bear.
