John 13:23-26

There was leaning on Jesus's bosom That is, sitting next to him at table. This phrase only expresses the then customary posture at meals, where the guests all leaned sideways on couches, and each was said to lie in the bosom of him who was placed next above him; one of the disciples whom Jesus loved This was John, the memory of whose sweet disposition, and other amiable qualities, is perpetuated in the peculiar love which Jesus bare to him. He always avoids with great care the expressly naming himself. Perhaps our Lord now gave him the first proof of his peculiar love, by disclosing this secret to him. Simon Peter, therefore Not daring to ask Jesus himself; beckoned to him The word νευει, thus rendered, might be more exactly translated, nodded, namely, he intimated his desire by a motion of his head; that he should ask him privately who it should be Peter was probably desirous to know, not only that he might be sure it was not himself, but that, knowing who it was, he and the other disciples might withdraw from him, and guard against him, as also, if possible, prevent his design. It may appear to us a desirable thing to know who, in the church, will deceive us, yet let this suffice: Christ knows, though we do not. He then, lying on Jesus's breast That is, leaning backward, and secretly whispering; saith, Lord, who is it? Jesus answered In his ear: so careful was he not to offend (if it had been possible) even Judas himself; He it is to whom I shall give a sop Το ψωμιον, the sop, which he took up while he was speaking; and when he had dipped the sop In a thick kind of sauce made of dates, raisins, and other ingredients beaten together and properly diluted; he gave it to Judas Iscariot Who took it readily enough, not suspecting the design of Christ's giving it to him. See note on Matthew 26:20. The Jews still retain the use of such a sauce, which they call haroseth, made of such kind of ingredients, about the consistence of mortar, to represent the clay in which their forefathers wrought while they were under bondage to the Egyptians.
