Mark 14:26-31 NRSV
When they had sung the hymn, they went out to the Mount of Olives. And Jesus said to them, “You will all become deserters; for it is written,
‘I will strike the shepherd,
and the sheep will be scattered.’
But after I am raised up, I will go before you to Galilee.” Peter said to him, “Even though all become deserters, I will not.” Jesus said to him, “Truly I tell you, this day, this very night, before the cock crows twice, you will deny me three times.” But he said vehemently, “Even though I must die with you, I will not deny you.” And all of them said the same.
