Exodus 1:17-22

But the midwives feared God, and did not do as the king of Egypt had commanded them, but let the boys live. So the king of Egypt called for the midwives and said to them, “Why have you done this thing, and let the boys live?” The midwives said to Pharaoh, “Because the Hebrew women are not as the Egyptian women; for they are vigorous and give birth before the midwife can get to them.” So God was good to the midwives, and the people multiplied, and became very mighty. Because the midwives feared God, He established households for them. Then Pharaoh commanded all his people, saying, “Every son who is born you are to cast into the Nile, and every daughter you are to keep alive.”
