A.T. Robertson Commentary Matthew 25:7

"Then all those virgins arose, and trimmed their lamps." — Matthew 25:7 (ASV)

Trimmed (εκοσμησαν). Put in order, made ready. The wicks were trimmed, the lights being out while they slept, fresh oil put in the dish, and lit again. A marriage ceremony in India is described by Ward (View of the Hindoos) in Trench's Parables: "After waiting two or three hours, at length near midnight it was announced, as in the very words of Scripture, 'Behold the bridegroom cometh; go ye out to meet him.'"
