The shipwreck at Malta, being later, is, of course, not referred to; so that no one of these three is on record.
A night and a day (νυχθήμερον)
A compound term occurring only here in the New Testament, and rarely in later Greek.
Have I been in the deep (ἐν τῷ βυθῷ πεποίηκα)
Lit., I have made (spent) a night and a day in the deep. For a similar use of ποιέω to make, see Act 15:33; Act 18:23; Act 20:3; Jam 4:13. βυθός bottom or depth occurs only here. Of the event itself there is no record.
