Isaiah 55
10 Ref For as the rain comes down, and the snow from heaven, and does not go back again, but gives water to the earth, and makes it fertile, giving seed to the planter, and bread for food;
11 Ref So will my word be which goes out of my mouth: it will not come back to me with nothing done, but it will give effect to my purpose, and do that for which I have sent it.
