verb | ἄριστον
23.20 · Physiological Processes and States · Eat, Drink
to eat a meal, to have a meal to eat a meal, without reference to any particular time of the day or to the type of food involved In some languages it is impossible to speak of ‘having a meal’ without indicating the time of day or the nature of the food consumed.
23.24 · Physiological Processes and States · Eat, Drink
to have breakfast to eat the earlier meal of the day Some scholars, however, interpret ἀριστάω in JHN 21:12 as meaning any kind of meal (see ἀριστάω[a], 23.20), and therefore one would translate as ‘Jesus said to them, Come have something to eat’ or ‘... have a meal.’
In a number of languages the earlier meal of the day may be spoken of as ‘the morning meal’ or ‘the first meal.’ In some languages it is actually called ‘the leftovers meal,’ but see the discussion on meals at different times of the day at 23.25.
