³ tn Grk “Iscariot, being of the number of the twelve.”

² sn The language of this verse is applied to Judas Iscariot in John 13:18.

¹ tn Grk “(not Iscariot).” The proper noun (Judas) has been repeated for clarity and smoothness in English style.

² sn Just as Peter is always mentioned first in all the lists, Judas Iscariot is always mentioned last, presumably because he was considered unworthy. There is some debate about what the name Iscariot means. It probably alludes to a region in Judea and thus might make Judas the only non-Galilean in the group. Several explanations for the name Iscariot have been proposed, but it is probably transliterated Hebrew with the meaning “man of Kerioth” (there are at least two villages that had that name). For further discussion see D. L. Bock, Luke (BECNT), 1:546; also D. A. Carson, John, 304.

¹ sn At least six explanations for the name Iscariot have been proposed, but it is probably transliterated Hebrew with the meaning “man of Kerioth” (there are at least two villages that had that name). See D. A. Carson, John, 304.

³ tn The word ἐπίγνωσις (epignōsis) could simply mean knowledge, but J. B. Mayor (Jude and Second Peter, 171-74) has suggested that it is often a fuller knowledge, especially in reference to things pertaining to spiritual truth. R. Bauckham (Jude, 2 Peter [WBC], 169-70) argues that it refers to the knowledge of God that is borne of conversion, but this is probably saying too much and is asking questions of the author that are foreign to his way of thinking. The term is used in 1:2, 3, 8; 2:20 (the verb form occurs twice, both in 2:21). In every instance it evidently involves being in the inner circle of those who connect to God, though it does not necessarily imply such a direct and relational knowledge of God for each individual within that circle. An analogy would be Judas Iscariot: Even though he was a disciple of the Lord, he was not converted.

² sn At this point the devil had already put into the heart of Judas Iscariot, Simon’s son, that he should betray Jesus. C. K. Barrett (St. John, 365) thought this was a reference to the idea entering the devil’s own heart, but this does not seem likely. It is more probable that Judas’ heart is meant, since the use of the Greek article (rather than a possessive pronoun) is a typical idiom when a part of one’s own body is indicated. Judas’ name is withheld until the end of the sentence for dramatic effect (emphasis). This action must be read in light of 13:27, and appears to refer to a preliminary idea or plan.

¹ sn The Greek word translated set…apart (ἁγιάζω, hagiazō) is used here in its normal sense of being dedicated, consecrated, or set apart. The sphere in which the disciples are to be set apart is in the truth. In 3:21 the idea of “practicing” (Grk “doing”) the truth was introduced; in 8:32 Jesus told some of his hearers that if they continued in his word they would truly be his disciples, and would know the truth, and the truth would make them free. These disciples who are with Jesus now for the Farewell Discourse have continued in his word (except for Judas Iscariot, who has departed), and they do know the truth about who Jesus is and why he has come into the world (17:8). Thus Jesus can ask the Father to set them apart in this truth as he himself is set apart, so that they might carry on his mission in the world after his departure (note the following verse).

¹ sn In Johannine thought the verb σκανδαλίζω (skandalizō) means to trip up disciples and cause them to fall away from Jesus’ company (John 6:61, 1 John 2:10). Similar usage is found in Didache 16:5, an early Christian writing from around the beginning of the 2nd century a.d. An example of a disciple who falls away is Judas Iscariot. Here and again in 16:4 Jesus gives the purpose for his telling the disciples about coming persecution: He informs them so that when it happens, the disciples will not fall away, which in this context would refer to the confusion and doubt which they would certainly experience when such persecution began. There may have been a tendency for the disciples to expect immediately after Jesus’ victory over death the institution of the messianic kingdom, particularly in light of the turn of events recorded in the early chapters of Acts. Jesus here forestalls such disillusionment for the disciples by letting them know in advance that they will face persecution and even martyrdom as they seek to carry on his mission in the world after his departure. This material has parallels in the Olivet Discourse (Matt 24-25) and the synoptic parallels.
