Proverbs 20:15-18

You may have an abundance of wealth, piles of gold and jewels, but there is something of far greater worth: speaking revelation-words of knowledge. Anyone stupid enough to guarantee a loan for a stranger deserves to have his property held as security. What you obtain dishonestly may seem sweet at first, but sooner or later you’ll live to regret it. If you solicit good advice, then your plans will succeed. So don’t charge into battle without wisdom, for wars are won by skillful strategy.
