john 18:11 Then said Jesus unto Peter, Put up thy sword into the sheath: the cup which my Father hath given me, shall I not drink it? - Free Bible Online

      11. Then said Jesus--"Suffer ye thus far" (Lu 22:51).
      Put up thy sword into the sheath: the cup which my Father hath given me, shall I not drink it?--This expresses both the feelings which struggled in the Lord's breast during the Agony in the garden--aversion to the cup viewed in itself, but, in the light of the Father's will, perfect preparedness to drink it. (See on Lu 22:39-46). Matthew adds to the address to Peter the following:--"For all they that take the sword shall perish by the sword" (Mt 26:52) --that is, 'Those who take the sword must run all the risks of human warfare; but Mine is a warfare whose weapons, as they are not carnal, are attended with no such hazards, but carry certain victory.' "Thinkest thou that I cannot now"--even after things have proceeded so far--"pray to My Father, and He shall presently give Me"--rather, "place at My disposal"--"more than twelve legions of angels"; with allusion, possibly, to the one angel who had, in His agony, "appeared to Him from heaven strengthening Him" (Lu 22:43); and in the precise number, alluding to the twelve who needed the help, Himself and His eleven disciples. (The full complement of a legion of Roman soldiers was six thousand). "But how then shall the scripture be fulfilled that thus it must be?" (Mt 26:53, 54). He could not suffer, according to the Scripture, if He allowed Himself to be delivered from the predicted death. "And He touched his ear and healed him" (Lu 22:51); for "the Son of man came not to destroy men's lives, but to save them" (Lu 9:56), and, even while they were destroying His, to save theirs.
