Exodus 1:15-17

And the king of Egypt spake to the Hebrew midwives, of which the name of the one was Shiphrah, and the name of the other Puah: and he said, When ye do the office of a midwife to the Hebrew women, and see them upon the stools; if it be a son, then ye shall kill him: but if it be a daughter, then she shall live. But the midwives feared God, and did not as the king of Egypt commanded them, but saved the men children alive.
