Exodus 1:6-11

Joseph died, and all his brothers and all that generation. But the sons of Israel were fruitful and increased greatly, and multiplied, and became exceedingly mighty, so that the land was filled with them. Now a new king arose over Egypt, who did not know Joseph. He said to his people, “Behold, the people of the sons of Israel are more and mightier than we. Come, let us deal wisely with them, or else they will multiply and in the event of war, they will also join themselves to those who hate us, and fight against us and depart from the land.” So they appointed taskmasters over them to afflict them with hard labor. And they built for Pharaoh storage cities, Pithom and Raamses.
