Arise, let us go. By these words he declares that, after having prayed, he was furnished with new arms. He had formerly, indeed, been sufficiently voluntary as to dying; but, when he came to the point, he had a hard struggle with the weakness of the flesh, so that he would willingly have withdrawn from dying, provided that he had been permitted to do so with the good-will of his Father. He, therefore, obtained by prayers and tears (Hebrews 5:7) new strength from heaven; not that he ever hesitated through want of strength, but because under the weakness of the flesh, which he had voluntarily undertaken, he wished to labor anxiously, and with painful and difficult exertion, to gain a victory for us in his own person. But now, when the trembling is allayed, and the fear is subdued, that he may again present a voluntary sacrifice to the Father, he not only does not retire or conceal himself, but cheerfully advances to death.

Rise, let us be going - That is, probably, "with them." Let us go wheresoever they shall lead us. The time when "I must die" is come. It is no longer proper to attempt an escape, and no more time can be given to repose.

Rise, let us be going - That is, to meet them, giving thereby the fullest proof that I know all their designs, and might have, by flight or otherwise, provided for my own safety; but I go willingly to meet that death which their malice designs me, and, through it, provide for the life of the world.

(12) Rise, let us be going: behold, he is at hand that doth betray me.
(12) Christ offers himself willingly to be taken, that in so obeying willingly he might make satisfaction for the wilful fall of man.

Rise, let us be going,.... Not to run away from the enemy, but to meet him: this was said, partly to arouse his sleepy disciples; and partly to show his love to his Father, and his submission to his will; as also to express the fortitude of his mind as man; he was now rid of his fears, and free from those agonies and dreadful apprehensions of things, he was but a little while ago possessed of; and likewise, to signify his willingness to be apprehended, and to suffer, and die, in the room of his people:
he is at hand that doth betray me. This shows his omniscience: he not only knew, as he did from the beginning, who should betray him; but he knew when be would do it; and he knew where the betrayer now was, that he was just now coming upon him, in order to deliver him the hands of sinful men. And this he spake with trepidity of soul, with greatness of mind, being no more concerned at it, than when he gave him the sop, and bid him do what he did quickly: he does not mention his name; nor did he ever, when he spoke of him as the betrayer; either because the disciples, as yet, did not fully and certainly know who should betray him, and he would not now surprise them with it; or because they did, and therefore it was needless to mention his name; or rather, because he was unworthy to be mentioned by name: a "behold" is prefixed to this, partly to awaken the attention of his disciples; and partly to express what an horrid, insolent, and unparalleled action that was, Judas was now about to be guilty of.

Rise, let us be going. It was no time for repose. Let them rouse, and go with him at once to confront the traitor and the band of enemies.
WAS CHRIST'S PRAYER ANSWERED?--The Epistle to the Hebrews (Hebrews 5:7) says it was. An angel came and strengthened him (Luke 22:43). There are two ways of answering a prayer for the removal of a burden. In one, the burden is taken away, and we remain the same; in the other, we are made so strong that the burden is no longer a burden to us; as what would crush a child, is but sport to a man.
