Luke omitted the story of Jesus' anointing in Bethany (Matt. 26:6-13; Mark 14:3-9; John 12:2-8). He had already narrated a similar event that happened on another occasion (7:36-50). By his omission Luke allowed the story of the plot to arrest Jesus to flow more smoothly.
22:3-4 Only Luke and John mentioned Satan's entering into Judas now (cf. John 13:2). Perhaps Luke wanted to clarify that Jesus' death was due to more than just human scheming (cf. Acts 5:3; 1 Cor. 2:8). It was part of a cosmic plan to destroy the God-man (cf. 4:1-12). Ironically Satan's participation in Jesus' arrest led to his own downfall (cf. Col. 2:15; Heb. 2:14). Luke also clarified Judas' identity for his readers (cf. 6:16) and noted Judas' contact with the officers of the temple guards. It was probably these soldiers along with Roman soldiers who arrested Jesus (cf. John 18:3). Perhaps Judas went to them because he originally anticipated Jesus being arrested in the temple area.
22:5-6 Judas was as hypocritical as the religious leaders; he, too, sought to avoid arousing the people. The theme of joy in Luke now crops up again, but this time it is joy in Jesus' enemies at the prospect of His fall.
