Proverbs 11:9-15

With his mouth the godless man would destroy his neighbor, but by knowledge the righteous are delivered. When it goes well with the righteous, the city rejoices, and when the wicked perish there are shouts of gladness. By the blessing of the upright a city is exalted, but by the mouth of the wicked it is overthrown. Whoever belittles his neighbor lacks sense, but a man of understanding remains silent. Whoever goes about slandering reveals secrets, but he who is trustworthy in spirit keeps a thing covered. Where there is no guidance, a people falls, but in an abundance of counselors there is safety. Whoever puts up security for a stranger will surely suffer harm, but he who hates striking hands in pledge is secure.
