Jerome — as excerpted in the Catena Aurea on Matthew 25:1-13

“Or, These virgins who complain that their lamps are gone out, shew that they are partially alight, yet have they not an unfailing light, nor enduring works. Whoso then has a virgin soul, and is a lover of chastity, ought not to rest content with such virtues as quickly fade, and are withered away when the heat comes upon them, but should follow after perfect virtues, that he may have an enduring light.”
