No man, when he hath lighted a candle. — Better, a lamp; and for “a candlestick,” the lampstand. See Notes on Matthew 5:15; Mark 4:21. In St. Matthew the proverb comes into the Sermon on the Mount; in St. Mark it occupies a position analogous to that in which it stands here, and this agreement favours the view that it was actually spoken in connection with the interpretation of the parable, as a special application of what had before been stated generally.
Note St. Luke’s more general term, “a vessel,” instead of “the bushel,” as in St. Matthew and St. Mark, and the somewhat wider range of the lamp’s illumining power, not only to those who are “in the house,” but to those also who are in the act of “entering” into it. We may, perhaps, venture to connect the choice of the latter phrase with St. Luke’s personal experience as a convert from heathenism. As such, he had been among those that entered into the house; and as he did so, he had seen the light of the lamp which the Apostles of Christ had lighted.
