John 13:26

“Jesus answered, he it is, etc.] Jesus replied, by whispering; for had he spoken out, the rest could not have been so ignorant, as they still continued, after the sign was given: Christ, I say, whispered to John, and told him by what sign he might know the person, and that it was he, to whom, says he, I shall give a sop, when I have dipped it. This was not the passover sop, which was dipped into a sauce made of various things, called by the Jews tswrj; for this was not the “paschal” supper, but a common supper at a private house, two days before the feast of the passover; but this sop, or rather crust of bread, which whether dipped into a liquid, or only a piece of dry bread, which Christ…”

“Jesus answered--also inaudibly, the answer being communicated to Peter perhaps from behind. He . . . to whom I shall give a sop when I have dipped it--a piece of the bread soaked in the wine or the sauce of the dish; one of the ancient ways of testifying peculiar regard; compare Joh 13:18, "he that eateth bread with Me." And when he had dipped . . . he gave it to Judas, &c.--Thus the sign of Judas' treachery was an affecting expression, and the last, of the Saviour's wounded love!”

“Jesus answered - That is, he answered John. It does not appear that either Judas or the other apostles heard him. Shall give a sop - The word translated “sop” means a morsel, a piece of bread, or anything else eaten - as much as we are accustomed to take at a mouthful. Jesus was about to dip it in the sauce which was used at the Passover. The word “dip,” in the original, is that from which is derived the word “baptize.” It means here that Jesus would dip it into the sauce as we do a piece of bread. It is probable that it was not an unusual thing for the master of a feast to help others in this way, as it does not appear to have attracted the attention of the others as at all remarkable. It…”

“Jesus answered - In his ear. So careful was he not to offend (if it had been possible) even Judas himself. The sop - Which he took up while he was speaking. He giveth it to Judas - And probably the other disciples thought Judas peculiarly happy! But when even this instance of our Lord's tenderness could not move him, then Satan took full possession. John 13:27”

“13:26 Meals included flat bread, which diners would dip into a common bowl. When Jesus gave a morsel to Judas (cp. Ruth 2:14), the disciples might have thought Jesus was honoring him. They did not understand what was occurring. They even thought that Judas’s departure (John 13:29) fulfilled an official duty for the feast! But Jesus was signaling to Judas that he understood Judas’s plan and was not taken by surprise. Jesus’ knowledge is profound and complete (see 1:48; 2:25).”

“He it is: Joh 13:30; Mat 26:23; Mar 14:19, Mar 14:20; Luk 22:21 sop: or, morsel Judas Iscariot: Joh 6:70, Joh 6:71, Joh 12:4-6 John 13:27”
