Lazarus of Bethany was a friend of Jesus and the brother of Mary and Martha whom, according to John 11, Jesus raised from the dead.
John 11:43-44 in the King James Version reads:
43 And when he thus had spoken, he cried with a loud voice, Lazarus, come forth. 44 And he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin. Jesus saith unto them, Loose him, and let him go.
These verses appear near the close of John 11, the chapter that recounts the raising of Lazarus. Read it in context at John 11:43-44, or the full chapter at John 11. Encyclopedia entry: en.wikipedia.org/wiki/Lazarus_of_Bethany.
