“But the wise ones
Took flasks of oil
With their lamps.”
αἱ δὲ φρόνιμοι ἔλαβον ἔλαιον ἐν τοῖς ἀγγείοις μετὰ τῶν λαμπάδων ἑαυτῶν.
This parable story is unique to Matthew. Jesus said that the wise bridesmaids took flasks of oil (αἱ δὲ φρόνιμοι ἔλαβον ἔλαιον ἐν τοῖς ἀγγείοις) with their lamps (μετὰ τῶν λαμπάδων ἑαυτῶν). Just the opposite of the foolish ones, the wise or prudent bridesmaids took extra oil in vessels with them, so that they were better prepared for the future. Their oil of righteousness made them ready for the bridegroom.
