Exodus 1:16-20

and he said, “When you are helping the Hebrew women to give birth and see them upon the birthstool, if it is a son, then you shall put him to death; but if it is a daughter, then she shall live.”

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 like 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.
