Proverbs 28:26

He that trusteth in his own heart; who trusts to his own wit, neglecting or slighting the advice of others, and the counsel of God himself. Is a fool; and shall receive the fruit of his folly, to wit, destruction. Whoso walketh wisely, distrusting his own judgment, and seeking the advice of others, and especially of God, as all truly wise men do, he shall be delivered from those dangers and mischiefs which fools bring upon themselves; whereby he showeth himself to be a wise man.
