Some answers only rase more questions...
It doesn't appear
to mean that at all.
After all, the verb is singular, so it applies only to him. What it appears
to mean literally
is that; he arrived, so did at least three others, and three of the others arrived before him.
Is this one of the subtleties of the Aorist tense? i.e. That because it makes implied reference to four actions (all four people arriving), that those actions must have therefore occurred simultaneously?
If I wanted to say, "he came fourth" in Greek. How would I do it? (I'm thinking perhaps through the use of the pluperfect tense.)
