“Five of them

Were foolish.

Five of them

Were wise.”

 

πέντε δὲ ἐξ αὐτῶν ἦσαν μωραὶ καὶ πέντε φρόνιμοι.

 

This parable story is unique to Matthew.  Jesus said that 5 of these bridesmaids were foolish or stupid (πέντε δὲ ἐξ αὐτῶν ἦσαν μωραὶ), while 5 were wise, intelligent, sensible or prudent (καὶ πέντε φρόνιμοι).  Thus, we have the wise prudent sensible ones and the foolish or stupid ones, equally split among these maidens.  This was like a metaphor for all humans, since half were good and half were bad.
