The Old Testament, in a sentence, is the story of God keeping His promises to one family. This lesson from Genesis 38:1 through 41:36 covers two key events within this family. In Chapter 38 we see the unusual way of how Judah, the fourth son of Jacob, fathers twins with Tamar. The line of the Messiah will come through one of these twins, Perez. In Chapter 39 and beyond, Joseph's life after arriving in Egypt is described, including his time in Potiphar's house and events that land him in jail. We learn how he, by the power of God, interpreted dreams while in jail that lead to Joseph finding favor with the Pharaoh of Egypt.
