Ramban on Genesis 33:5/רמב"ן על בראשית ל״ג:ה׳

1WHO ARE THESE WITH THEE? Esau inquired about the women and children, and Jacob modestly answered, The children whom G-d hath graciously given thy servant, as he did not want to say that they were his wives. Esau thereby understood that they were the mothers of the children.
