Exodus 1:14-16

14 And they made their lives bitter with hard work in mortar and in bricks, and in all [kinds of] work in the field; all their work in which they made them do [was] with harshness.

15 And the king of Egypt spoke to the Hebrew midwives, of which the name of the one [was] Shiphrah, and the name of the other Puah.

16 And he said, When you midwife the Hebrew women, and look on the birth stools, if it [is] a son, then you shall kill him. But if it [is] a daughter, then she shall live.
