Exodus 1:9-11

9 He said to his people, "See! The Israelite people have multiplied and become more numerous than we are!

10 Come, let us deal shrewdly with them to stop their increase; [6] otherwise, in time of war they too may join our enemies to fight against us, and so leave the land."

11 Accordingly, they set supervisors over the Israelites to oppress them with forced labor. [AD] Thus they had to build for Pharaoh [7] the garrison cities of Pithom and Raamses.
