Exodus 1:17-19

17But the midwives feared God, and did not do as the king of Egypt commanded them, but saved the male children alive.

18So the king of Egypt called for the midwives and said to them, “Why have you done this thing, and saved the male children alive?”

19And the midwives said to Pharaoh, “Because the Hebrew women are not like the Egyptian women; for they are lively and give birth before the midwives come to them.”
