'Mandrakes' in the Bible

Some time later, during the wheat harvest season, Reuben went out and found some mandrakes in the field and brought them back for his mother Leah. Then Rachel told Leah, "Please give me your son's mandrakes."

In response, Leah asked her, "Wasn't it enough that you've taken away my husband? Now you also want to take my son's mandrakes!" But Rachel replied, "Okay, let's let Jacob sleep with you tonight in exchange for your son's mandrakes."

When Jacob came in from the field that evening, Leah went to meet him and told him, "You're having sex with me tonight. I traded my son's mandrakes for you!" So he slept with her that night.
