Judas the betrayer was present at the sacramental service. He received from Jesus the emblems of His broken body and His spilled blood. He heard the words, "This do in remembrance of Me." And sitting there in the very presence of the Lamb of God, the betrayer brooded upon his own dark purposes, and cherished his sullen, revengeful thoughts. At the feet washing, Christ had given convincing proof that He understood the character of Judas. "Ye are not all clean" (John 13:11), 654 He said. These words convinced the false disciple that Christ read his secret purpose. Now Christ spoke out more plainly. As they were seated at the table He said, looking upon His disciples, "I speak not of you all: 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."

Forræderen Judas var til stede ved den hellige nadvertjeneste. Han modtog af Jesus symbolerne på hans sønderbrudte legeme og hans udgydte blod. Han hørte ordene: "Gør dette til ihukommelse af mig!" Og medens han sad der, hvor selve Guds Lam var til stede, rugede han over sine egne mørke planer og var opfyldt af sine egne vrede og hævngerrige tanker. Ved fodtvætningen havde Kristus givet overbevisende bevis for, at han kendte Judas karakter. "I er ikke alle rene" (Joh. 13,11), sagde han. Disse ord overbeviste den falske discipel om, at Kristus kendte hans hemmelige planer. Nu sagde Kristus det mere tydeligt. Da de sad sammen ved bordet, sagde han, medens han så på sine disciple: "Jeg taler ikke om jer alle; jeg ved, hvem jeg har udvalgt; men det skriftord måtte jo gå i opfyldelse: Den, som spiser mit brød, har løftet sin hæl imod mig."
