Exodus 1:11-13

Amplified Bible

¹¹ 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. ¹² But the more the Egyptians oppressed them, the more they multiplied and expanded, so that the Egyptians dreaded and were exasperated by the Israelites. ¹³ And the Egyptians made the Israelites serve rigorously [forcing them into severe slavery].
