Exodus 5:6

So they appointed taskmasters over them to afflict them with hard labors. And they built for Pharaoh storage cities, Pithom and Raamses.

So the taskmasters of the people and their foremen went out and spoke to the people, saying, “Thus says Pharaoh, ‘I am not going to give you any straw.

Moreover, the foremen of the sons of Israel, whom Pharaoh’s taskmasters had set over them, were beaten and were asked, “Why have you not completed your required amount either yesterday or today in making brick as previously?”

and he spoke to them according to the counsel of the young men, saying, “My father made your yoke heavy, but I will add to your yoke; my father disciplined you with whips, but I will discipline you with scorpions.”
