Mark 14:26-31

26When they had sung the hymn, they went out to the Mount of Olives. 27And Jesus said to them, "You will all become deserters; for it is written,
'I will strike the shepherd,
and the sheep will be scattered.'

28But after I am raised up, I will go before you to Galilee." 29Peter said to him, "Even though all become deserters, I will not." 30Jesus said to him, "Truly I tell you, this day, this very night, before the cock crows twice, you will deny me three times." 31But he said vehemently, "Even though I must die with you, I will not deny you." And all of them said the same.
