Today there are four chapters.
John 18 is commonly called Jesus’ high priestly prayer. In some conservative circles it is also called “The Lord’s prayer.” In it Jesus prays for himself, then he prays for his disciples, and then he prays for all future believers. In the end of the chapter he prays that the believers will see his glory, the glory God gave him before the creation of the world.
Genesis 37 tells of Joseph’s dreams, outrageous as they were they made his brothers jealous, so they sold him into slavery to Potiphar in Egypt.
Genesis 38 tells the story of Judah and Tamar. one of the rules of the Old Testament is that if a man dies without producing an heir, it was the duty of his brother to try to produce and offspring to his widow. Onan shirked this responsibility, and that was the sin of Onan. Tamar is thus still barren, so she tricks Judah. You can read it for yourself. Judah finally confesses: She is more righteous than I.
Genesis 39 then picks up the story of Joseph and Potiphar’s wife. This is a classic, and for doing the right thing he is falsely accused, and thrown in jail.
