Whoever keeps his mouth and his tongue keeps his soul from troubles.
A furious horse needs a bridle to restrain its fierceness, and it seems the tongue of man needs more than a double bridle to keep it in from doing hurt. The wise man never ceases to admonish us about this point. As a high-spirited horse, if its fury is not curbed with a strong hand, will hurry its rider along, without regarding pits, or precipices, or deep waters, and expose him to extreme jeopardy of his life, so an unbridled tongue will make a man hateful to God and men, plunge him into contentions and debates, and expose his estate, and life, and credit, to extreme danger. Who is the man that wishes to enjoy a quiet and peaceable life? Let him set a guard over his mouth, and refrain his tongue from profaneness and corrupt communication, from railing and reviling, and all evil speaking, from foolish talking, and from inconvenient jesting. Let prudence and the fear of God stand continually like sentinels at the door of his lips.
(George Lawson, D. D.)
