On the Principle that the Worse is accustomed to be always plotting against the Better (61-65)

To him therefore the answer brought praise, as he confessed that virtue without the divine favour was not sufficient of itself to help any one; and, in consequence, it [*] [*]

But Cain here speaks arrogantly, "Am I my brother’s keeper?" For we might altogether say he was sure hereafter to lead a miserable life, if nature made you the guardian and keeper of so good a man. Do you not see that the lawgiver entrusts the keeping and preservation of the holy things not to any chance person, but to the Levites, who were the most holy persons in their opinions? for whom the earth and the air and the water were considered an unworthy inheritance, but the heaven and the whole world were looked upon as their due. And the Creator alone is worthy of these things, to whom they have fled for refuge, becoming his sincere suppliants and servants, showing their love for their master in their continued service, and in the unhesitating observance of all the commands which are laid upon them, and in the preservation of the things entrusted to them.

And it has not fallen to the lot of all the suppliants to become guardians of the holy things, but to those only who have arrived at the number fifty, which proclaims remission of offences and perfect liberty and a return to their ancient possessions. "For this," says the Scripture, "is the law concerning the Levites: from twenty-five years old and upwards, they shall go in to wait upon the service of the tabernacle of the congregation: and from the age of fifty years they shall cease waiting upon the service thereof, and shall serve no more; but shall minister with their brethren in the tabernacle of the congregation, and they shall keep what is to be kept, and shall do no service."

Therefore, the Scripture charges him who has half perfection (for the number fifty is perfect, and the number twenty-five is the half of fifty), to work and to do what is holy, approving his ministration by his works. And the beginning, as an old writer has said, is half of the whole. But the perfect man it does not enjoin to labour any longer, but only to preserve what he has acquired by labour and diligence. For [*]

subsequently practise therefore is mediocrity not perfection, for it takes place not in perfect souls, but in such as are seeking after perfection. But it is the perfect duty of guardianship to deliver to memory the well-practised contemplations of holy things, the excellent deposit of knowledge to a faithful guardian, who is the only one who disregards the ingenious and manifold nets of forgetfulness; so that the Scripture, with great propriety and felicity, calls him who is mindful of what he has learnt, the guardian of it.
