Mark 5:7
Context5:7 Then 1 he cried out with a loud voice, “Leave me alone, 2 Jesus, Son of the Most High God! I implore you by God 3 – do not torment me!”
Mark 5:19
Context5:19 But 4 Jesus 5 did not permit him to do so. Instead, he said to him, “Go to your home and to your people and tell them what the Lord has done for you, 6 that he had mercy on you.”


[5:7] 1 tn Grk “And.” Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the narrative.
[5:7] 2 tn Grk “What to me and to you?” (an idiom). The phrase τί ἐμοὶ καὶ σοί (ti emoi 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 OT 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 own, 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). These nuances were apparently expanded in Greek, but the basic notions of defensive hostility (option 1) and indifference or disengagement (option 2) are still present. 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….”
[5:7] 3 sn Though it seems unusual for a demon to invoke God’s name (“I implore you by God”) in his demands of Jesus, the parallel in Matt 8:29 suggests the reason: “Why have you come to torment us before the time?” There was an appointed time in which demons would face their judgment, and they seem to have viewed Jesus’ arrival on the scene as an illegitimate change in God’s plan regarding the time when their sentence would be executed.
[5:19] 4 tn Grk “And.” Here καί (kai) has been translated as “but” to indicate the contrast present in this context.
[5:19] 5 tn Grk “he”; the referent (Jesus) has been specified in the translation for clarity.
[5:19] 6 sn Jesus instructs the man to declare what the Lord has done for him, in contrast to the usual instructions (e.g., 1:44; 5:43) to remain silent. Here in Gentile territory Jesus allowed more open discussion of his ministry. D. L. Bock (Luke [BECNT], 1:781) suggests that with few Jewish religious representatives present, there would be less danger of misunderstanding Jesus’ ministry as political.
