John Gill Commentary Genesis 33:7

"And Leah also and her children came near, and bowed themselves: and after came Joseph near and Rachel, and they bowed themselves." — Genesis 33:7 (ASV)

And Leah also with her children came near, and bowed themselves Who were in the next division or company; their children were seven, Reuben, Simeon, Levi, Judah, Issachar, Zebulun, and Dinah, six sons and one daughter: and after came Joseph near and Rachel, and they bowed themselves ; it is observed that Joseph is mentioned before his mother; it may be, because they might put him before her in the procession, for greater safety; or she might present him to Esau, being a child of little more than six years of age, and teach him how to make his obeisance to him, which she also did herself.
