Luke 5:39

Verse 39. Having drunk old wine, &c. Wine increases its strength and flavour, and its mildness and mellowness, by age, and the old is therefore preferable. They who had tasted such mild and mellow wine would not readily drink the comparatively sour and astringent juice of the grape as it came from the press. The meaning of this proverb in this place seems to be this: You Pharisees wish to draw my disciples to the austere and rigid duties of the ceremonial law--to fasting and painful rites; but they have come under a milder system. They have tasted the gentle and tender blessings of the gospel; they have no relish for your stern and harsh requirements.
