Thomas Aquinas,
Summa Theologiae — Question 117 - OF LIBERALITY…
“ It belongs to a virtuous man not only to make good use of his matter or instrument, but also to provide opportunities for that good use. Thus it belongs to a soldier's fortitude not only to wield his sword against the foe, but also to sharpen his sword and keep it in its sheath. Thus, too, it belongs to liberality not only to use money, but also to keep it in preparation and safety in order to make fitting use of it. ”
