8. ἑτοίμασον τί δειπνήσω. Here the τί becomes equivalent to a relative, para quod comedam. Comp. Mat 10:19, δοθήσεται ὑμῖν … τί λαλήσετε, quod dicatis. Winer, p. 210.
ἕως φάγω. ‘Till I have eaten’ (which I am going certainly to do; hence no ἂν is needed).
φάγεσαι. The Hellenistic Greek φάγομαι is used as a future, as Greek authors use ἔδομαι, Jam 5:3; Rev 17:16.
