The disciples recognized the Lord Jesus in the Breaking of the Bread.

"Then Jesus said to them, “You foolish people! You find it so hard to believe all that the prophets wrote in the Scriptures.  Wasn’t it clearly predicted that the Messiah would have to suffer all these things before entering his glory?”
(Luke 24:25-26 NLT)

"They asked each other, “Were not our hearts burning within us while he talked with us on the road and opened the Scriptures to us?”
(Luke 24:32 NIV)

“It is true! The Lord has risen and has appeared to Simon.”   (Luke 24:34 NIV)
