Chapter 38 — Part IV: Prayer — The Fourth Petition: Give Us This Day Our Daily Bread

Section 24. Not only do we beg of God to grant us to use, with the aid of His goodness, the fruit of our virtuous toil -- and that is truly called ours -- but we also pray for a good mind, that we may be able well and prudently to use what we have honestly acquired.
