Exodus 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. שפרה SHIPHRAH — This was Jochebed; she bore this additional name because she used to put the babe after its birth into good physical condition (משפרת) by the care she bestowed upon it (Sotah 11b). פועה PUAH — This was Miriam, and she bore this additional name because she used to Call aloud and speak and croon to the babe just as women do who soothe a child when it is crying (Sotah 11b). פועה has the meaning of crying aloud, as (Isaiah 42:14) “I will cry (אפעה) like a travailing woman”.
