Isaiah 55:10-12 (NIV)
10 As the rain and the snow come down from heaven, and
do not return to it without watering the earth and making it bud
and flourish, so that it yields seed for the sower and bread for
11 so is my word
that goes out from my mouth: It will not return to me empty, but
will accomplish what I desire and achieve the purpose for which
I sent it.
12 You will go
out in joy and be led forth in peace; the mountains and hills will
burst into song before you, and all the trees of the field will
clap their hands.
