And preach as you go, saying, `The kingdom of heaven is at hand.' Heal the sick, raise the dead, cleanse lepers, cast out demons. You received without paying, give without pay.

Matthew 10:7-8

Idleness is the enemy of the soul; and therefore the brethren ought to be employed in manual labor at certain times, at others, in devout reading.

- St. Benedict of Nursia, 'The Rule of Saint Benedict'
