It was the same day as the resurrection. Two disciples — one named Cleopas, one unnamed — were walking the seven miles from Jerusalem to Emmaus, talking through everything that had happened. Their grief was fresh. They had hoped Jesus was the one to redeem Israel. Now he was dead, the tomb was apparently empty, and some women were claiming angels. Their walking and talking is a picture of disorientation: they had believed something with their whole lives, it had failed, and they were trying to make sense of the rubble.
A stranger joined them on the road. The stranger asked what they were discussing. Cleopas's response is heartbreaking in its incredulity: "Art thou only a stranger in Jerusalem, and hast not known the things which are come to pass there in these days?" You are the only person in this city who doesn't know? The stranger — Jesus — responded by asking, "What things?" He made them tell it. They rehearsed the whole story: the prophet mighty in deed and word, their hope that he would redeem Israel, the crucifixion, the empty tomb, the women's vision of angels. They laid it all out.
Then he answered them. He called them foolish and slow of heart to believe the prophets, and he proceeded to walk them through the entire Old Testament — "beginning at Moses and all the prophets" — explaining how it all pointed to the Christ suffering before entering his glory. They walked seven miles. He had a lot of ground to cover. When they reached Emmaus, the stranger made as if to continue, and they urged him to stay. He came in and sat at table with them.
