Matthew 23:5 But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments, [kjv]
παντα δε τα εργα αυτων ποιουσιν προς το θεαθηναι τοις ανθρωποις πλατυνουσιν γαρ τα φυλακτηρια αυτων και μεγαλυνουσιν τα κρασπεδα [gnt]
The ancient Greek word
"μεγας" ≈ "great" and is the source of the English prefix
"mega".
The Greek word for
"border" is, literally, the words for "
mixture" and "
shackle" (as something used to "
bind" someone, previous verse).
This word is used in only one verse in the
LXX (Septuagint) and the follow-on word is
"wings" as in a "
bird"
"wing". This could be a subtle reference to the "
birds".
