Exodus 1:8-12

Now a new king arose over Egypt, who did not know Joseph [nor the history of his accomplishments]. He said to his people, “Behold, the people of the sons of Israel are too many and too mighty for us [they greatly outnumber us]. Come, let us deal shrewdly with them, so that they will not multiply and in the event of war, join our enemies, and fight against us and escape from the land.” So they set taskmasters over them to oppress them with hard labor. And the sons of Israel built Pithom and Raamses as storage cities for Pharaoh. But the more the Egyptians oppressed them, the more they multiplied and expanded, so that the Egyptians dreaded and were exasperated by the Israelites.
