Lucas 24:33-34

Cleopas and his friend’s eagerness to return to tell the other disciples that Jesus had appeared to them confirms the reality of His resurrection. They could not keep the good news to themselves. There were others back in Jerusalem that did not know it and needed to hear it. When they returned, they discovered that "the Lord" had also appeared to Peter. No New Testament writer described this appearance in detail (cf. 1 Corinthians 15:5).

Thus Luke included a second testimony to the Resurrection. The women and Peter had witnessed the empty tomb, and now these two disciples and Peter bore witness to the Resurrection. "Simon" was Peter’s normal Jewish name.
