Matthew 25:7

Trimmed their lamps - Burning until midnight, the oil was exhausted: they gave a dim and obscure light. They trimmed them by removing the burnt parts of the linen or the torch, so that they would burn clear. It was needful, also, to dip them again in oil, or to pour oil upon them. This strikingly represents the conduct of most people at the approach of death. They then begin to make ready. They are alarmed, anxious, and trembling, and then they ask the aid of others, but often when it is forever too late.
