Genesis 34:5

(5) Jacob heard.—As Dinah did not return home (Genesis 34:26), her father probably learned her dishonour from the maidservants who had gone out with her. But “he held his peace,” chiefly from his usual cautiousness, as being no match for the Hivites, but partly because Leah’s sons had the right to be the upholders of their sister’s honour.
