Exodus 1:15-20

Then the king of Egypt spoke to the Hebrew midwives, of whom the name of one was Shiphrah and the name of the other Puah; and he said, “When you do the duties of a midwife for the Hebrew women, and see them on the birthstools, if it is a son, then you shall kill him; but if it is a daughter, then she shall live.” But the midwives feared God, and did not do as the king of Egypt commanded them, but saved the male children alive. So the king of Egypt called for the midwives and said to them, “Why have you done this thing, and saved the male children alive?”

And 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.”

Therefore God dealt well with the midwives, and the people multiplied and grew very mighty.
