Midrash for Kiddushin 4:11

He cast down Sammael and his troop from their holy place in heaven, and cut off the feet of the serpent, and decreed that it should cast its skin and suffer pain once in seven years in great pain, and cursed it || that it should drag itself with its belly (on the ground), and its food is turned in its belly into dust and the gall of asps, and death is in its mouth, and He put hatred between it and the children of the woman, so that they should bruise its head, and after all these (curses comes) death. He gave the woman nine curses and death: the afflictions arising from menstruation and the tokens of virginity; the affliction of conception in the womb; and the affliction of child-birth; and the affliction of bringing up children; and her head is covered like a mourner, and it is not shaved except on account of immorality, and her ear is pierced like (the ears of) perpetual slaves; and like a hand-maid she waits upon her husband; and she is not believed in (a matter of) testimony; and after all these (curses comes) death.
