Jesus the Christ A Study of the Messiah and His Mission...

In saying to the Twelve, whose feet He had washed, "Ye are clean," the Lord had specified an exception by His after remark, "but not all." John, the recorder, takes care to explain that Jesus had in mind the traitor, and, "therefore said he, Ye are not all clean." The guilty Iscariot had received without protest the Lord's service in the washing of his recreant feet, though after the ablution he was spiritually more filthy than before. When Jesus had again sat down, the burden of His knowledge concerning the treacherous heart of Judas again found expression. "I speak not of you all," He said, "I know whom I have chosen: but that the scripture may be fulfilled, He that eateth bread with me hath lifted up his heel against me."[1203] The Lord was intent on impressing the fact of His foreknowledge as to what was to come, so that when the terrible development was an accomplished fact, the apostles would realize that thereby the scriptures had been fulfilled. Troubled in spirit, He reiterated the dreadful assertion that one of those present would betray Him. Peter made signs to John, who occupied the place next to Jesus and was at that moment leaning his head on the Lord's breast, that he ask which of them was the traitor. To John's whispered inquiry the Lord replied: "He it is, to whom I shall give a sop, when I have dipped it."

There was nothing unusual for a person at table, particularly the host, to dip a piece of bread into the dish of gravy or savory mixture, and hand it to another. Such action on the part of Jesus attracted no general attention. He dipped the morsel of bread and gave it to Judas Iscariot, with the words: "That thou doest, do quickly." The others understood the Lord's remark as an instruction to Judas to attend to some duty or go upon some errand of ordinary kind, perhaps to purchase something for the further celebration of the Passover, or to carry gifts to some of the poor, for Judas was the treasurer of the party and "had the bag." But Iscariot understood. His heart was all the more hardened by the discovery that Jesus knew of his infamous plans, and he was maddened by the humiliation he felt in the Master's presence. After the sop, which he had opened his mouth to receive from the Lord's hand, "Satan entered into him" and asserted malignant mastership. Judas went out immediately, abandoning forever the blessed company of his brethren and the Lord. John chronicles the traitor's departure with the terse and ominous remark, "and it was night."
