Ezekiel 23:18-21

When she carried on her prostitution openly and exposed her naked body, I turned away from her in disgust, just as I had turned away from her sister. Yet she became more and more promiscuous as she recalled the days of her youth, when she was a prostitute in Egypt. There she lusted after her lovers, whose genitals were like those of donkeys and whose emission was like that of horses. So you longed for the lewdness of your youth, when in Egypt your bosom was caressed and your young breasts fondled.
