“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.”
Matthew 25:10 — Greek Interlinear
Church Fathers on Matthew 25:10
Hom. lxxviii, In the foregoing parable the Lord set forth the punishment of the man who beat, and was drunk, and wasted his Lord’s goods; in this He declares his punishment who profits not, and does not prepare for himself abundantly the things of which he has need; for the foolish virgins had oil, but not enough.

By 'the kingdom of heaven' is meant the present Church, as in that, 'The Son of Man shall send forth his angels, and they shall gather out of his kingdom all things that offend.' [Matt 13:41]
