John Gill Commentary Acts 27:33

"And while the day was coming on, Paul besought them all to take some food, saying, This day is the fourteenth day that ye wait and continue fasting, having taken nothing." — Acts 27:33 (ASV)

And while the day was coming on
Between midnight and break of day: Paul besought them all to take meat; to sit down and eat a meal together:

saying, this day is the fourteenth day that you have tarried ;
or have been waiting for, or expecting; that is, as the Arabic version expresses it, a shipwreck; for fourteen days past, ever since the storm begun, they had expected nothing but shipwreck and death:

and continued fasting, having taken nothing :
not that they had neither ate nor drank all that while, for without a miracle they could never have lived so long without eating something; but the meaning is, they had not eaten anyone regular meal all that while, had only caught up a bit now and then, and ate it, and that but very little.
