There are two other noble uses of the tongue to which reference is constantly made in our book; the _Instruction of the ignorant_, and the _Championship of the distressed_. With regard to the first, we are told that "the lips of the wise disperse knowledge," while of course the heart of the foolish not being right cannot possibly impart rightness to others.[350] It is only the wise in heart that can claim the title of prudent, but where that wisdom is "the sweetness of the lips increaseth learning."[351] "The heart of the wise instructeth his mouth and addeth learning to his lips."[352] The lips of knowledge are compared to a precious vessel which is more valuable than gold or rubies.[353] To teach well requires earnest preparation, "the heart of the righteous studieth to answer."[354] But when the right answer to the pupil is discovered and given it is beautifully compared to a kiss on the lips.[355] But never is the tongue more divinely employed than in using its knowledge or its pleadings to deliver those who are in danger or distress. "Through knowledge the righteous may often be delivered."[356] The mouth of the upright will deliver those against whom the wicked are plotting.[357] It is a great prerogative of wise lips that they are able to preserve not themselves only but others.[358] The true and faithful witness delivers souls.[359] It is this which gives to power its one great attraction for the good man. The ruler, the judge, the person of social consideration or of large means is in the enviable position of being able to "open his mouth for the dumb, in the cause of all such as are left desolate, to judge rightly and minister judgment to the poor and needy."[360] The Press--that great fourth estate--which represents for us the more extended use of the tongue in modern times, illustrates in the most vivid way the service which can be rendered where speech is fit, and also the injury that can be done where it is rash, imprudent, dishonest, interested, or unjust.
