In Parshat Vayishlach Yaakov divides his group into two camps so that if one is attacked the other might escape. How did he divide people between them? Did Leah go in one and Rachel in the other, for example? How were his children divided? Were they equal camps, or was the idea that he could position a battle-ready camp to protect a camp containing all the weaker people?
Later when he meets Esav an order is given, but that seems to be one ordered procession, not two separate groups.
