Midrash su Salmi 94:9

The Caesar said to Rabban Gamaliel: "He who created the mountains has not created the wind, and He who created the wind did not create the mountain, for it is written (Amos 4, 13) He that formed the mountains and created the wind." And he answered: "If so, then concerning a man, of whom it reads (Gen. 1, 27) And God created, and (Ib. 2, 7) Arid the Lord God formed, should also mean that he who has formed has not created, and vice versa. There is in the human body one span square, in which two holes are to be found — [one in the nose and one in the ear]. Will you then say that he who created one of them did not create the other, for it is said (Ps. 94, 9) He that hath planted the ear, shall He not hear? Or he that hath formed the eye, shall He not see?" And the Min said: "Yea, I am of this opinion." "How is it," rejoined Gamaliel, "that when death comes, are then both creators agreed, [to kill their creation together]?" A magician said to Rabban Gamaliel: "Thy upper half belongs to Ormuzd, thy lower half to Ahriman." "If this be so," answered he, "why does Ahriman allow Ormuzd to let the water pass through his dominion, to the ground?"
