Bede the Venerable — as excerpted in the Catena Aurea on Luke 19:11-27

“The first servant is the order of teachers sent to the circumcision, who received one pound to put out to use, inasmuch as it was ordered to preach one faith. But this one pound gained ten pounds, because by its teaching it united to itself the people who were subject to the law. It follows, And he said unto him, Well done, thou good servant: because thou hast been faithful in a very little, &c. The servant is faithful in a very little who does not adulterate the word of God. For all the gifts we receive now are but small in comparison of what we shall have.”
