On the Tilling of the Earth by Noah (26-30)

We have now therefore explained, in what respect, the occupation of tilling the ground differs from husbandry, and a tiller of the ground from a husbandman. And we must now consider whether there are not some other species akin to these already mentioned, but which, through the common names borne by them and others, conceal the real difference which exists between them. At least there are two which we have discovered by investigation, concerning which we will say what is fitting, if it is in our power.

Therefore, as we found a tiller of the earth and a husbandman, though there did not appear to be any difference between them (till we came to investigate the allegorical meaning concealed under each name), nevertheless very far removed from one another in fact, such also shall we find to be the case with a shepherd and a keeper of sheep. For the lawgiver sometimes speaks of the occupation of a shepherd, and sometimes of that of a keeper of sheep.

And those who do not examine expressions with any excessive accuracy, will perhaps fancy that these two appellations are synonimous terms for the same

For if it is customary to give both the names of shepherd and keeper of sheep to those who have the management of flocks, still they do not give these names to that reason which is the superintendant of the flock of the soul; for a man who is but an indifferent manager of a flock is called a keeper of sheep, but a good and faithful one is called a shepherd, and in what way we will proceed to show immediately.

Nature has made cattle akin to every individual among us, the soul putting forth two young branches as from one root; one of which being entire and undivided, and being left in its integrity is called the mind; but the other part is separated by six divisions into seven natures, five outward senses, and two other organs, the organs of speech, and that of generation.
