*CER:  indicates a non-literal, but good translation.  In the first example here, the verb “ἔρχεται” is present tense, which in the indicative mood often can be rendered in the aorist tense, since it expresses linear action not in the present but at some point in the past.  The designation CER is equivalent to “Contextual English Rendering”.
