Isaiah 55:10-11

The rain and the snow come down from the sky, and they do not immediately return there. Instead, they give water to the earth, so that crops will grow there. Then the farmer has seeds to plant, and people have food to eat. It is the same when I give my word to people. It will not return to me without any result. No! My word does what I want it to do. What I promise to do will certainly happen.’
