Through patience a ruler can be persuaded, and a gentle tongue can break a bone. Proverbs 25:15

Be patient and you will finally win, for a soft tongue can break hard bones. (Proverbs 28:13)

The ear that heareth the reproof of life abideth among the wise (Proverbs 15:31).

Take fast hold of instruction; let her not go: keep her; for she is thy life (Proverbs 4:13).

Where there is no counsel, the people perish; but in the multitude of counselors there is safety. [Proverbs 29:18; 11:14]

He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction (Proverbs 13:3).
