Exodus 1
7 Ref And the children of Israel were fruitful, and increased abundantly, and multiplied, and waxed exceeding mighty; and the land was filled with them.
8 Ref Now there arose up a new king over Egypt, which knew not Joseph.
9 Ref And he said unto his people, Behold, the people of the children of Israel are more and mightier than we:
10 Ref Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and so get them up out of the land.
11 Ref Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh treasure cities, Pithom and Raamses.
12 Ref But the more they afflicted them, the more they multiplied and grew. And they were grieved because of the children of Israel.
