“בן הכנענית THE SON OF THE CANAANITISH WOMAN — means the son of Dinah, who had been associated with a Canaanite (Shechem). When they (her brothers) had killed Shechem, Dinah refused to leave the city until Simeon swore to her that he would marry her and regard the child she was about to bear as his own (cf. Genesis Rabbah 80:11).”
“Jamuel. Numbers xxvi. 12, he is called Namuel. — Jachin is Jarid [ Jarib ?] , 1 Paralipomenon iv. 24. (Calmet)”
