Genesis 33:6

Then the handmaids came near, they and their children ,.... Being foremost, and next to, Jacob, as Bilhah and her two sons, Dan and Naphtali, and Zilpah and her two sons, Gad and Asher:

and they bowed themselves ; in token of respect to Esau, as Jacob had done before them, and set them an example, and no doubt instructed them to do it.
