Exodus 1:17-19

But the midwives feared God, and did not as the king of Egypt commanded them, but saved the men-children alive. And the king of Egypt called for the midwives, and said unto them, Why have ye done this thing, and have saved the men-children alive? And the midwives said unto Pharaoh, Because the Hebrew women are not as the Egyptian women; for they are lively, and are delivered ere the midwife come unto them.
