Exodus 1:15-21

15 The king of Egypt spoke to the Hebrew midwives, of whom the name of the one was Shiphrah, and the name of the other Puah,  16 and he said, "When you perform the duty of a midwife to the Hebrew women, and see them on the birth stool; if it is a son, then you shall kill him; but if it is a daughter, then she shall live."  17 But the midwives feared God, and didn't do what the king of Egypt commanded them, but saved the baby boys alive.  18 The king of Egypt called for the midwives, and said to them, "Why have you done this thing, and have saved the men-children alive?"

19 The midwives said to Pharaoh, "Because the Hebrew women aren't like the Egyptian women; for they are vigorous, and give birth before the midwife comes to them."

20 God dealt well with the midwives, and the people multiplied, and grew very mighty.  21 It happened, because the midwives feared God, that he gave them families.
