Genesis 33:2

And he put the handmaids and their children foremost,.... In the first division, as being less honourable and less beloved by him:

and Leah and her children after; still according to the degree of honour and affection due unto them; Leah being a wife that was imposed and forced upon him:

and Rachel and Joseph hindermost; being most beloved by him, and therefore most careful of them; Rachel being his principal and lawful wife, and who had the greatest share in his affection, and Joseph his only child by her.
