Chapters 41 through 44 of the book are covered in this lesson.
Joseph rises to power in Egypt and the sons of Jacob enter Egypt, from Canaan, seeking food.
Jacob's sons, Joseph's brothers, unknowingly fulfill Joseph's dream they had resented back in 37:5-8. Joseph begins a series of tests to determine how his brother's treat their father and Benjamin, the youngest.
At the end, when Judah mediates with his father Jacob, and with Joseph, and shows himself willing to be enslaved in place of his brother, this prefigures the saving work of his descendant, Jesus, who gave Himself as a mediator, ransom, and sacrifice for the world.
