Exodus 1:12-14

12 But the more they afflicted them, the more they multiplied and grew, so much that they loathed the sons of Israel.

13 And the Egyptians made the sons of Israel serve with rigor,

14 and they made their lives bitter with hard bondage, [making] mortar and brick and in all manner of service in the field; all their service, in which they made them serve, [was] with rigor.
