[4:34] 1 tn Grk “What to us and to you?” This is an idiom meaning, “We have nothing to do with one another,” or “Why bother us!” The phrase τί ἡμῖν καὶ σοί (ti Jhmin kai soi) is Semitic in origin, though it made its way into colloquial Greek (BDAG 275 s.v. ἐγώ). The equivalent Hebrew expression in the Old Testament had two basic meanings: (1) When one person was unjustly bothering another, the injured party could say “What to me and to you?” meaning, “What have I done to you that you should do this to me?” (Judg 11:12; 2 Chr 35:21; 1 Kgs 17:18). (2) When someone was asked to get involved in a matter he felt was no business of his, he could say to the one asking him, “What to me and to you?” meaning, “That is your business, how am I involved?” (2 Kgs 3:13; Hos 14:8). Option (1) implies hostility, while option (2) merely implies disengagement. BDAG suggests the following as glosses for this expression: What have I to do with you? What have we in common? Leave me alone! Never mind! Hostility between Jesus and the demons is certainly to be understood in this context, hence the translation: “Leave me alone….” For a very similar expression, see Luke 8:28 and (in a different context) John 2:4.
[4:34] 2 sn The confession of Jesus as the Holy One here is significant, coming from an unclean spirit. Jesus, as the Holy One of God, who bears God’s Spirit and is the expression of holiness, comes to deal with uncleanness and unholiness.
[19:42] 3 sn On this day. They had missed the time of Messiah’s coming; see v. 44.
[19:42] 4 tn Grk “the things toward peace.” This expression seems to mean “the things that would ‘lead to,’ ‘bring about,’ or ‘make for’ peace.”
[19:42] 5 sn But now they are hidden from your eyes. This becomes an oracle of doom in the classic OT sense; see Luke 13:31-35; 11:49-51; Jer 9:2; 13:7; 14:7. They are now blind and under judgment (Jer 15:5; Ps 122:6).
