Deuteronomy 15

The Hebrew lent to the nations at interest. He did not himself receive doctrine from the people but handed it down. To him the Lord opened his treasury so that the rain of his word might make the nations to grow wet and so that he might become the prince among the nations, but he himself would have no prince over himself.

Just as that law, Deuteronomy 15: There shall be no needy person or beggar among you, was not given against the mendicancy of the poor, but against the tightfistedness of the rich — which is clear from the fact that in the same chapter it is added: The poor shall not be wanting in the land of your habitation; therefore I command you to open your hand to your needy and poor brother — so also this law is given to bishops who have abundance for the sustenance of poor clerics, especially those who are not in want voluntarily but by compulsion, lest on account of their indigence they become slack in divine service.

What did Moses mean by making this prohibition, except to forbid those who have begun to live aright to engage in human occupations? To plow with the firstborn of a cow is to display the beginnings of one's conversion in carrying out public activities. To shear the firstborn of sheep is to strip the cover of secrecy from our first good works and display them to human eyes. Therefore we are forbidden to work with the firstlings of cattle. When we are kept from shearing the firstlings of the sheep, we should not act openly too quickly, even if we have begun some solid work. Since our life begins as something simple and innocuous, it is proper that we should not lay aside the covering of its privacy, lest it show itself naked to human eyes once the wool has been sheared. The firstlings of cattle and sheep are suitable only for divine sacrifices. Whatever we begin with that is strong, simple and innocent, we should offer on the altar of our hearts to the honor of the secret judge. And he without a doubt receives it more gladly if it has been hidden from men and not stained with any desire for praise. But often the beginnings of a new conversion are mixed with elements of a carnal life and hence should not become known too quickly. Otherwise, when the good that is acceptable is praised, the soul is deceived by praise and cannot grasp the evils that still lie concealed in it.
