"Chapter 22—Moses This chapter is based on Exodus 1 to Exodus 4 . The people of Egypt, in order to supply themselves with food during the famine, had sold to the crown their cattle and lands, and had finally bound themselves to perpetual serfdom. Joseph wisely provided for their release; he permitted them to become royal tenants, holding their lands of the king, and paying an annual tribute of one fifth of the products of their labor. PP 241"
"Now these are the names of the children of Israel, which came into Egypt; every man and his household came with Jacob. Reuben, Simeon, Levi, and Judah, Issachar, Zebulun, and Benjamin, Dan, and Naphtali, Gad, and Asher."
The passage explicitly states that the chapter is based on Exodus 1-4, which includes the account of the Israelites in Egypt.
"But the children of Jacob were not under the necessity of making such conditions. On account of the service that Joseph had rendered the Egyptian nation, they were not only granted a part of the country as a home, but were exempted from taxation, and liberally supplied with food during the continuance of the famine. The king publicly acknowledged that it was through the merciful interposition of the God of Joseph that Egypt enjoyed plenty while other nations were perishing from famine. He saw, too, that Joseph's management had greatly enriched the kingdom, and his gratitude surrounded the family of Jacob with royal favor. PP 241.2"
"And Joseph placed his father and his brethren, and gave them a possession in the land of Egypt, in the best of the land, in the land of Rameses, as Pharaoh had commanded. And Joseph nourished his father, and his brethren, and all his father’s household, with bread, according to their families."
This passage describes how Joseph provided for his family in Egypt, giving them land and sustenance, which parallels the description of the Israelites' favorable treatment.
"But as time rolled on, the great man to whom Egypt owed so much, and the generation blessed by his labors, passed to the grave. And “there arose up a new king over Egypt, which knew not Joseph.” Not that he was ignorant of Joseph's services to the nation, but he wished to make no recognition of them, and, so far as possible, to bury them in oblivion. “And he said unto his people, Behold, the people of the children of Israel are more and mightier than we: come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and so get them up out of the land.” PP 241.3"
"Now there arose up a new king over Egypt, which knew not Joseph. And he said unto his people, Behold, the people of the children of Israel are more and mightier than we: Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and so get them up out of the land."
The passage directly quotes and alludes to Exodus 1:8, which introduces the new king who did not know Joseph and began to oppress the Israelites.
