Comentario sobre Exodo 1:15

למילדת (the Piel participle) — This is synonymous with מולידות (the Hiphil participle, and both denote the women who assist the mother in bringing the child to birth). But some verbs are used in forms of a light conjugation (i. e. one which has no strong Dagesh as a characteristic) or in forms of a strong conjugation (one that has such a Dagesh), as e. g., שׁוֹבֵר (Kal) and מְשַׁבֵּר (Piel); דּוֹבֵר (Kal) and מְדַבֵּר (Piel). both having the same meaning; similarly here we may have מוליד (the Hiphil — without a strong Dagesh) or מְיַלֵּד (the Piel), both signifying one who helps to bring to birth.

למילדות העבריות; the ones who were Jewish.

למילדות העבריות, to the midwives resident in the capital. It was obviously impossible for such a large number of people residing in so many different parts of Egypt, to all be serviced by only two midwives. However, after the midwives in the capital, though Egyptian, betrayed the instructions by their king and explained to their king why they had done so, the king did not bother to rely on midwives anywhere else either, and the scheme was abandoned.
