“That very day two of them were going to a village named Emma′us, about seven miles from Jerusalem, and talking with each other about all these things that had happened. While they were talking and discussing together, Jesus himself drew near and went with them. But their eyes were kept from recognizing him. And he said to them, “What is this conversation which you are holding with each other as you walk?” And they stood still, looking sad.”
Luke 24:13-17
