ἐνέχω

imperfect ἐνεῖχον; (present passive ἐνέχομαι); to have within, to hold in;
a. passive to be held, be entangled, be held ensnared, with a dative of the thing in which one is held captive — very often in Greek writings, both literally (as τῇ πάγη, Herodotus 2, 121, 2) and figuratively (as ἀγγελία, Pindar Pythagoras 8, 69; φιλοτιμία, Euripides, Iph. A. 527; κακῷ, Epictetus diss. 3, 22, 93): ζυγῷ δουλείας, Gal 5:1; (θλίψεσιν, 2 Thess 1:4 WH marginal reading) (ἀσεβείαις, 3Macc. 6:10).
b. ἐνέχω τίνι, to be enraged with, set oneself against, hold a grudge against someone: Mk 6:19; Lk 11:53 (Gen 49:23); the expression is elliptical, and occurs in full (χόλον τίνι to have anger in oneself against another) in Herodotus 1, 118; 8, 27; 6, 119; see a similar ellipsis under προσέχω. (In this last case the ellipsis supplied is τόν νοῦν, Winers Grammar, 593 (552); Buttmann, 144 (126); Meyer, et al., would supply the same after ἐνέχειν in Mark and Luke the passages cited and render the phrase to have (an eye) on, watch with hostility; but DeWette, Bleek, others, agree with Grimm. Many take the expression in Luke, the passage cited outwardly, to press upon (R. V. text); see Stephanus Thesaurus, under the word; Liddell and Scott, under the word; Hesychius ἐνέχει. μνησικακεῖ. ἔγκειται.)
