Isaiah 55:10-11

For, as come down doth the shower, And the snow from the heavens, And thither returneth not, But hath watered the earth, And hath caused it to yield, and to spring up, And hath given seed to the sower, and bread to the eater, So is My word that goeth out of My mouth, It turneth not back unto Me empty, But hath done that which I desired, And prosperously effected that [for] which I sent it.
