Exodus 1:6-14

And Joseph died, all his brothers, and all that generation. But the children of Israel were fruitful and increased abundantly, multiplied and grew exceedingly mighty; and the land was filled with them. Now there arose a new king over Egypt, who did not know Joseph. And he said to his people, “Look, the people of the children of Israel are more and mightier than we; come, let us deal shrewdly with them, lest they multiply, and it happen, in the event of war, that they also join our enemies and fight against us, and so go up out of the land.” Therefore they set taskmasters over them to afflict them with their burdens. And they built for Pharaoh supply cities, Pithom and Raamses. But the more they afflicted them, the more they multiplied and grew. And they were in dread of the children of Israel. So the Egyptians made the children of Israel serve with rigor. And they made their lives bitter with hard bondage—in mortar, in brick, and in all manner of service in the field. All their service in which they made them serve was with rigor.
