On the road to Emmaus, two disciples were discouraged because they had lost faith in Jesus Christ, that he failed in redeeming Israel. Then, Jesus preached to these 2 disciples the greatest sermon in the history of world, as he expounded all the scriptures in Moses and the prophets concerning him. They did not even understand this greatest sermon, but their hearts did burn within them. Then, when they returned to Jerusalem, Jesus appears a second time to the disciples and opened their understanding for all the scriptures concerning his death and resurrection.
