Exodus 1:1-14 ESV
These are the names of the sons of Israel who came to Egypt with Jacob, each with his household: Reuben, Simeon, Levi, and Judah, Issachar, Zebulun, and Benjamin, Dan and Naphtali, Gad and Asher. All the descendants of Jacob were seventy persons; Joseph was already in Egypt. Then Joseph died, and all his brothers and all that generation. But the people of Israel were fruitful and increased greatly; they multiplied and grew exceedingly strong, so that the land was filled with them.
Now there arose a new king over Egypt, who did not know Joseph. And he said to his people, “Behold, the people of Israel are too many and too mighty for us. Come, let us deal shrewdly with them, lest they multiply, and, if war breaks out, they join our enemies and fight against us and escape from the land.” Therefore they set taskmasters over them to afflict them with heavy burdens. They built for Pharaoh store cities, Pithom and Raamses. But the more they were oppressed, the more they multiplied and the more they spread abroad. And the Egyptians were in dread of the people of Israel. So they ruthlessly made the people of Israel work as slaves and made their lives bitter with hard service, in mortar and brick, and in all kinds of work in the field. In all their work they ruthlessly made them work as slaves.
