The text is available only because it is quoted within a letter written by Clement in Alexandria in the 2nd century. It starts out innocuously enough. The story is so familiar that we feel sure we know the name of the young man who had died, even though it is not specified here. The longer of the 2 passages is to be inserted after Mark 10:46. The text of that passage is this:
And they come into Bethany. And a certain woman whose brother had died was there. And, coming, she prostrated herself before Jesus and says to him, 'Son of David, have mercy on me.' But the disciples rebuked her. And Jesus, being angered, went off with her into the garden where the tomb was, and straightway a great cry was heard from the tomb. And going near Jesus rolled away the stone from the door of the tomb. And straightway, going in where the youth was, he stretched forth his hand and raised him, seizing his hand. But the youth, looking upon him, loved him and began to beseech him that he might be with him. And going out of the tomb they came into the house of the youth, for he was rich. And after six days Jesus told him what to do and in the evening the youth comes to him, wearing a linen cloth over his naked body. And he remained with him that night, for Jesus taught him the mystery of the kingdom of God. And thence, arising, he returned to the other side of the Jordan.
