Matthew 15:37 (tr. Robert K. Brown), in
The New Greek-English Interlinear New Testament ... Translators: Robert K. Brown and Philip W. Comfort (Wheaton: Tyndale House Publishers, Inc., 1990), p. 60:
AND EVERYONE-ATE AND THEY WERE SATISFIED AND THE LEFTOVERS OF THE FRAGMENTS WERE SEVEN BASKETS FULL.
The Greek (from the United Bible Societies' 4th corrected edition):
καὶ ἔφαγον πάντες καὶ ἐχορτάσθησαν καὶ τὸ περισσεῦον τῶν κλασμάτων ἦραν ἑπτὰ σπυρίδας πλήρεις.
Brown seems to have regarded
ἦραν as some form of the copulative verb
εἰμί (perhaps confusing it with the imperfect
ἦσαν), but in fact it's the aorist of the transitive verb
αἴρω = lift up, remove.
