출애굽기 1:18의 주석

מדוע 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.”

מדוע לא עשיתם…זתחיינן את הילדים? "Why did you not do…and you kept these children alive?" What did the king refer to when he asked the midwives: "why did you do, etc?" Their crime was what they had not done! Not killing the babies surely is not described as an activity! The king should have asked: "why did you not do etc.?" Furthermore, what did the king mean when he accused the midwives of keeping the children alive? If he referred to the fact that they supplied food and water, how did the midwives' answer satisfy him? Their answer would be equivalent to rebellion against the king's command!

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