you hear this: Christ said to Peter, "Put up thy sword in its sheath." He did not say, Put it away, throw it from thee. For Christ blames him because he seeks it first, and not because he has it at his side—otherwise he would have blamed him long before, if that were wrong.

Therefore Christ speaks: There is no use in protecting and guarding me further. The hour foreseen
