Psalms 34:12-13

Psalms 34:12-13. And loveth many days, that he may see good? Keep thy tongue from evil and thy lips from speaking guile.

He begins with one of the hardest practical duties of the fear of God for he that bridleth his tongue is able also be bridle the whole body. The tongue is such an unruly member that if that be kept - and only through grace can it be so - then we may be quite certain that all the other organs and faculties will be kept, too.
