then Jesus said to his disciples: "Your faith all will be shaken. for it is written: I will strike the shepherd and the sheep will be scattered. but after I rise up, I will go before you into Galilee." petrus said to him: "even if their faith all will be shaken, I'm not."

"another disciples saying that, too."
