▼tn Grk “he”; the referent (Jesus) has been specified in the translation for clarity.

▼sn Jesus here demonstrated the absurdity of the thinking of those who maintained that he was in league with Satan and that he actually derived his power from the devil. He first teaches (vv. 17-20) that if he casts out demons by the ruler of the demons, then in reality Satan is fighting against himself, with the result that his kingdom has come to an end. He then teaches (v. 21-22) about defeating the strong man to prove that he does not need to align himself with the devil because he is more powerful. Jesus defeated Satan at his temptation (4:1-13) and by his exorcisms he clearly demonstrated himself to be stronger than the devil. The passage reveals the desperate condition of the religious leaders, who in their hatred for Jesus end up attributing the work of the Holy Spirit to Satan.

▼tn Or “is left in ruins.”

▼tn Grk “and house falls on house.” This phrase pictures one house collapsing on another, what is called today a “house of cards.”

▼tn Here δέ (de) has been translated as “so” to indicate that the clause that follows is a logical conclusion based on the preceding examples.

▼tn This first class condition, the first of three “if” clauses in the following verses, presents the example vividly as if it were so. In fact, all three conditions in these verses are first class. The examples are made totally parallel. The expected answer is that Satan’s kingdom will not stand, so the suggestion makes no sense. Satan would not seek to heal.

▼tn Grk “because.” “I ask you this” is supplied for the sake of English.

▼sn Most read your sons as a reference to Jewish exorcists (cf. “your followers,” L&N 9.4; for various views see D. L. Bock, Luke [BECNT], 2:1077-78), but more likely this is a reference to the disciples of Jesus themselves, who are also Jewish and have been healing as well (R. J. Shirock, “Whose Exorcists are they? The Referents of οἱ υἱοὶ ὑμῶν at Matthew 12:27/Luke 11:19,” JSNT 46 [1992]: 41-51). If this is a reference to the disciples, then Jesus’ point is that it is not only him, but those associated with him whose power the hearers must assess. The following reference to judging also favors this reading.

▼tn The pronoun “them” is not in the Greek text, but is implied. Direct objects were frequently omitted in Greek when clear from the context.

▼sn The finger of God is a figurative reference to God’s power (L&N 76.3). This phrase was used of God’s activity during the Exodus (Exod 8:19).

▼sn The kingdom of God is a major theme of Jesus’ teaching. The nature of the kingdom of God in the NT and in Jesus’ teaching has long been debated by interpreters and scholars, with discussion primarily centering around the nature of the kingdom (earthly, heavenly, or both) and the kingdom’s arrival (present, future, or both). An additional major issue concerns the relationship between the kingdom of God and the person and work of Jesus himself. See Luke 6:20; 11:20; 17:20-21.

▼tn The phrase ἔφθασεν ἐφ᾿ ὑμᾶς (ephthasen eph’ humas) is important. Does it mean merely “approach” (which would be reflected in a translation like “has come near to you”) or actually “come upon” (as in the translation given above, “has already overtaken you,” which has the added connotation of suddenness)? The issue here is like the one in 10:9 (see note there on the phrase “come on”). Is the arrival of the kingdom merely anticipated or already in process? Two factors favor arrival over anticipation here. First, the prepositional phrase “upon you” suggests arrival (Dan 4:24, 28 Theodotion). Second, the following illustration in vv. 21-23 looks at the healing as portraying Satan being overrun. So the presence of God’s authority has arrived. See also L&N 13.123 for the translation of φθάνω (phthanō) as “to happen to already, to come upon, to come upon already.”
