Exodus 1:13

10 come, let us deal wisely with them, lest they multiply, and it come to pass, that, when there falleth out any war, they also join themselves unto our enemies, and fight against us, and get them up out of the land.

11 Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh store-cities, Pithom and Raamses.

12 But the more they afflicted them, the more they multiplied and the more they spread abroad. And they were grieved because of the children of Israel.

13 And the Egyptians made the children of Israel to serve with rigor:

14 and they made their lives bitter with hard service, in mortar and in brick, and in all manner of service in the field, all their service, wherein they made them serve with rigor.

15 And the king of Egypt spake to the Hebrew midwives, of whom the name of the one was Shiphrah, and the name of the other Puah:

16 and he said, When ye do the office of a midwife to the Hebrew women, and see them upon the birth-stool; if it be a son, then ye shall kill him; but if it be a daughter, then she shall live.
