Psalms 34:13

Keep thy tongue from evil, and thy lips from speaking guile.

Ver. 13. Keep thy tongue from evil, &c.] This is a hard saying, think the most; who will therefore rather venture it than yield to be so tied up. The tongue is an unruly member, and can hardly be hampered. But who would not temper his tongue, and bind it to the good abearance, for true blessedness? Who would not rather bite it off, and spit it out (as that ancient martyr did his, into the face of the tyrant, who solicited him to deny Christ), than miss heaven? Ficinus after his tract De sanitate tuenda, of keeping good health; and another, of recovering health; and a third, of prolonging life; because all will not do, wisely addeth a fourth, of laying hold on eternal life; which cannot be done but by mortifying this earthly member, a loose and lewd tongue. For by thy words thou shalt be justified, and by thy words thou shalt be condemned, saith the Judge himself, Matthew 12:37 : compare Genesis 49:21, with Deuteronomy 33:23, and it will appear that good words ingratiate with God and men.
