Ezekiel 23:18-21

So she discovered her whoredoms, and discovered her nakedness: then my mind was alienated from her, like as my mind was alienated from her sister. Yet she multiplied her whoredoms, in calling to remembrance the days of her youth, wherein she had played the harlot in the land of Egypt. For she doted upon their paramours, whose flesh is as the flesh of asses, and whose issue is like the issue of horses. Thus thou calledst to remembrance the lewdness of thy youth, in bruising thy teats by the Egyptians for the paps of thy youth.
