Exodus 1:11, 15-17, 8

So they appointed taskmasters over them to afflict them with hard labor. And they built for Pharaoh storage cities, Pithom and Raamses.

Then the king of Egypt spoke to the Hebrew midwives, one of whom was named Shiphrah and the other was named Puah; and he said, “When you are helping the Hebrew women to give birth and see them upon the birthstool, if it is a son, then you shall put him to death; but if it is a daughter, then she shall live.” But the midwives feared God, and did not do as the king of Egypt had commanded them, but let the boys live.

Now a new king arose over Egypt, who did not know Joseph.
