John Cassian, The Institutes X.22: How the brethren in Egypt work with their hands, not only to supply their own needs, but also to minister to those who are in prison

How the brethren in Egypt work with their hands, not only to supply their own needs, but also to minister to those who are in prison.

And so taught by these examples the Fathers in Egypt never allow monks, and especially the younger ones, to be idle, estimating the purpose of their hearts and their growth in patience and humility by their diligence in work; and they not only do not allow them to receive anything from another to supply their own wants, but further, they not merely refresh pilgrims and brethren who come to visit them by means of their labours, but actually collect an enormous store of provisions and food, and distribute it in the parts of Libya which suffer from famine and barrenness, and also in the cities, to those who are pining away in the squalor of prison; as they believe that by such an offering of the fruit of their hands they offer a reasonable and true sacrifice to the Lord.
