hot pertaining to being hot, often associated with boiling In REV 3:15 the usage is figurative; ζεστός in the sense of a favorable attitude towards something seems not to have been a conventionalized meaning.
In a number of languages the contrast between ‘hot’ and ‘cold’ may refer primarily to sex or anger, in which case the contrast is certainly not appropriate for REV 3:15. It may therefore be necessary in many instances to use an equivalent such as ‘for or against’ or ‘friendly to or hostile toward.’
