Sforno on Exodus 1:18/ספורנו על שמות א׳:י״ח

1מדוע עשיתם, “why did you betray my trust?” After all, when I gave you these instructions you did not refuse the task, making me believe that you would indeed cause the death of these boy babies. “My trust has been betrayed.”

2ותחיינה את הילדים, not only did you not kill these babies, but you were actively involved in ensuring their survival!
