UBS Dictionary of the Greek New Testament

Sense 1: unapproachable, that which cannot be approached

Semantic entry: 15.80

Semantic domains: Linear Movement

Subdomains: Come Near, Approach

Definition: pertaining to not being capable of being approached

Notes: It may be necessary to indicate, either in the text or in a marginal note, the reason why the light cannot be approached, for one could interpret this passage to mean that the light was either so small as not to be generally visible or so far away that it could not be reached. If, however, one uses a term for ‘light’ which implies extreme intensity of light, then the context should indicate the basis for its being unapproachable.
