Sforno on Numbers 11:12/ספורנו על במדבר י״א:י״ב

1האנוכי הריתי, true, a natural father knows how to guide his children even if they have differences of opinions among them. The reason such a father can be successful is that all his children know that he loves them all and has their best interests at heart. But these people do not put their trust in me at all; they suspect me and constantly provoke me to see what I would do for them.
