John Lightfoot on Luke 15:8

[A woman lighteth a candle.] There is a parable not much unlike this in Midras Schir, "R. Phineas Ben Jair expoundeth. If thou seek wisdom as silver, that is, if thou seek the things of the law as hidden treasures--A parable. It is like a man who if he lose a shekel or ornament in his house, he lighteth some candles, some torches, till he find it. If it be thus for the things of this world, how much more may it be for the things of the world to come!"
