Exodus 1:15-16

15Then the king of Egypt spoke to the Hebrew midwives, one of whom 1was named Shiphrah, and the other 2was named Puah;

16and he said, “When you are helping the Hebrew women to give birth and see them upon the birthstool, 3if it is a son, then you shall put him to death; but if it is a daughter, then she shall live.”
