39.1 · (ἀντιτάσσομαι) · Hostility, Strife · Opposition, Hostility
to oppose, to be hostile toward, to show hostility to oppose someone, involving not only a psychological attitude but also a corresponding behavior It may be that in some languages one can best render ἀντιτάσσομαι in ACT 18:6 as ‘to speak against,’ though in some languages opposition is often expressed idiomatically as ‘to show a sour face toward,’ ‘to have a mean heart toward,’ or ‘to turn one’s back on.’
1 There are probably certain significant distinctions in meaning in the various verbs listed in 39.1, but on the basis of NT usage it is not possible to determine precisely what these distinctions may be.
