1 tn Grk “the Cananean,” but according to both BDAG 507 s.v. Καναναῖος and L&N 11.88, this term has no relation at all to the geographical terms for Cana or Canaan, but is derived from the Aramaic term for “enthusiast, zealot” (see Luke 6:15; Acts 1:13), possibly because of an earlier affiliation with the party of the Zealots. He may not have been technically a member of the particular Jewish nationalistic party known as “Zealots” (since according to some scholars this party had not been organized at that time), but simply someone who was zealous for Jewish independence from Rome, in which case the term would refer to his temperament.
2 sn 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.
3 tn Grk “who even betrayed him.”
