Exodus 1:16-19

16“When you are helping the Hebrew women during childbirth on the delivery stool, if you see that the baby is a boy, kill him; but if it is a girl, let her live.” 17The midwives, however, feared God and did not do what the king of Egypt had told them to do; they let the boys live.

18Then the king of Egypt summoned the midwives and asked them, “Why have you done this? Why have you let the boys live?”

19The midwives answered Pharaoh, “Hebrew women are not like Egyptian women; they are vigorous and give birth before the midwives arrive.”
