Believable?

Better is a poor man who walks in his integrity
Than he who is perverse in speech and is a fool. - Proverbs 19:1

There are simply too many ways to prove this proverb of Solomon. Are you likely to believe, trust, follow, or rely on a person you know to be a liar, curser, or slanderer? Every day every work you speak is important to how people trust you. Are you gaining believability or being looked at as a fool?
