And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
All Commentaries on Matthew 25:10 Go To Matthew 25
Hilary of Poitiers
AD 368
Because the foolish were not able to go out and meet the bridegroom, since their lamps had gone out, they asked the wise to share their oil. They replied that they could not give them oil for there would perhaps not be enough. They told them to go to the dealers and buy for themselves. These foolish were not part of the group entering the wedding feast but late and unworthy of entering. They had lost their opportunity.
