Charles H. Spurgeon on Psalms 34:13

Keep thy tongue from evil, etc. Ficinus, after his tracts, 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. Mt 12:37. Compare Ge 49:21, with De 33:23, and it will appear that good words ingratiate with God and man. John Trapp.
