Exodus 1:11-13

11 So the Egyptians put slave drivers over them to crush their spirits with hard labor. The Israelites built the cities of Pithom and Rameses to serve as supply centers for the king.

12 But the more the Egyptians oppressed the Israelites, the more they increased in number and the farther they spread through the land. The Egyptians came to fear the Israelites

13 and made their lives miserable by forcing them into cruel slavery. They made them work on their building projects and in their fields, and they had no pity on them.
