“‘When I broke
The five loaves
For the five thousand,
How many baskets
Full of broken pieces
Did you collect’”
They said to him.
‘Twelve.’”
ὅτε τοὺς πέντε ἄρτους ἔκλασα εἰς τοὺς πεντακισχιλίους, πόσους κοφίνους κλασμάτων πλήρεις ἤρατε; λέγουσιν αὐτῷ Δώδεκα.
This is similar to Matthew, chapter 16:9, as Jesus clearly reminded them of the two times that he had multiplied the loaves of bread. Was that not good enough for them? Did they not remember that first he broke the 5 loaves of bread for the 5,000 people (ὅτε τοὺς πέντε ἄρτους ἔκλασα εἰς τοὺς πεντακισχιλίους)? Then he asked them how many fragments of the broken pieces had they gathered in the hand baskets (πόσους κοφίνους κλασμάτων πλήρεις ἤρατε). They responded to him that there were 12 baskets left over (λέγουσιν αὐτῷ Δώδεκα), after everyone had eaten. All this had taken place recently as recorded in chapter 6:30-44.
