《易传·象传下·归妹》
 嫁出的少女作为偏房 ，这是婚嫁中的正常情况； 好像跛脚而奋力向前行走 ，说明能以偏房侧室的地位辅佐和照顾丈夫，必获吉祥。 幽居之人利于守正 ，这是因为能遵守恒常的规则。 妹妹想冒充姐姐的地位嫁为正室 ，这是不正当的。
跛能履吉，相承也。利幽人之贞，未变常也。归妹以须，未当也。愆期之志，有待而行也。
Marrying out a young girl as a concubine is a normal situation in marriage. It is like limping and trying hard to move forward, indicating that she can assist and take care of her husband as a concubine and side concubine, and will surely be auspicious. It is beneficial for the secluded to stick to the right way because they can abide by the constant rules. It is not right for a younger sister to pretend to marry as a wife.
