The Value Of Silver (Ecclesiastes 10:19).
‘A feast is made for laughter, and wine gladdens the life, and silver answers all things.'
The thought here would seem to be that feasting and wine temporarily produce merriment but that a man's wealth is the mainstay of his whole life. The wise man will therefore make sure that his wealth is preserved and will not fritter it away in feasting and drinking and fruitless activities.
Or the idea may be that while a feast and wine bring a kind of happiness, it is only silver which can be fully persuasive with regard to life.
