Friday

as the rain and snow fall from the heavens and return not again, but water the earth, bringing forth life and giving growth, seed for sowing and bread for eating; So is my word that goes forth from my mouth; it will not return to me empty; But it will accomplish that which I have purposed and prosper in that for which I sent it.                            Canticle 10 (from Isaiah chapter 55) 
          my word will not return to me empty
