Exodus 1:9-14

9“Look,” he said to his people, “the Israelites have become far too numerous for us.

10Come, we must deal shrewdly with them or they will become even more numerous and, if war breaks out, will join our enemies, fight against us and leave the country.” 11So they put slave masters over them to oppress them with forced labor, and they built Pithom and Rameses as store cities for Pharaoh. 12But the more they were oppressed, the more they multiplied and spread; so the Egyptians came to dread the Israelites 13and worked them ruthlessly.

14They made their lives bitter with harsh labor in brick and mortar and with all kinds of work in the fields; in all their harsh labor the Egyptians worked them ruthlessly.
