Exodus 1:11-14

11So the Egyptians appointed taskmasters over the Israelites to oppress them with forced labor. As a result, they built Pithom and Rameses as store cities for Pharaoh. 12But the more they were oppressed, the more they multiplied and flourished; so the Egyptians came to dread the Israelites.

13They worked the Israelites ruthlessly 14and made their lives bitter with hard labor in brick and mortar, and with all kinds of work in the fields. Every service they imposed was harsh.
