Isaiah 55:10-11

New Revised Standard Version Catholic Edition

¹⁰ For as the rain and the snow come down from heaven,
    and do not return there until they have watered the earth,
making it bring forth and sprout,
    giving seed to the sower and bread to the eater,
¹¹ so shall my word be that goes out from my mouth;
    it shall not return to me empty,
but it shall accomplish that which I purpose,
    and succeed in the thing for which I sent it.
