2 - Thus coming, she speaks to us in a voice that knows our desires, arguing for their satiation. 3 - She always comes promising great pleasure in the guise of wholesomeness. Oil is a figure used often in the Scripture, for a variety of things. It is used as a symbol for the Holy Spirit. It was used in consecrating men and objects to the Lord's service.
Oil has medicinal properties and speaks of soothing and restoration.
Lamps gave light, consuming oil as their fuel, and when one visited a home oil was used to anoint their heads both refreshment, and as a sign of dignity and favor. All of these could be capitalized on in terms of the subject before us. But it is that peculiar property of oil noted in the verse that the Author desires to bring to our minds for consideration. Just as Temptation speaks the language of our lusts, just as it coats its allurements in that which is sweet and innocent in itself, so too, its method of persuasion is to remove the inward friction of the soul that would make participation in the sin seem strident and harmful. The oil of Temptation's persuasion makes sin comfortable - where it ought to produce great pain.
