Aphrahat the Persian Sage, on Isa 55:10

“And as the rain and the snow come down from heaven, and return no more thither, but soak the earth, and water it, and make it to spring, and give seed to the sower, and bread to the eater:”

“For the rain and the snow do not return to heaven but accomplish in the earth the will of him that sends them. So the word that he shall send through his Christ, who is himself the Word and the Message, shall return to him with great power. For when he shall come and bring it, he shall come down like rain and snow, and through him all that is sown shall spring up and bear righteous fruit, and the word shall return to his sender; but not in vain shall his going have been, but thus shall he say in the presence of his sender, "Behold, I and the children that the Lord has given me." And this is the voice through which the dead shall live. And this is the voice of God that shall sound from on high and raise up all the dead.”
