In what I have hitherto said, you easily find, that I do not talk of bearing witness in general, which is and may be lawful upon a thousand accounts in relation to property and other matters, and wherein there are many scandalous corruptions, almost peculiar to this country, which would require to be handled by themselves. But I have confined my discourse only to that branch of bearing false witness, whereby the public is injured in the safety or honour of the prince, or those in authority under him. In order therefore to be a faithful witness, it is first necessary that a man doth not undertake it from the least prospect of any private advantage to himself. The smallest mixture of that leaven will sour the whole lump. Interest will infallibly bias his judgment, although he be ever so firmly resolved to say nothing but truth. He cannot serve God and Mammon; but as interest is his chief end, he will use the most effectual means to advance it. He will aggravate circumstances to make his testimony valuable; he will be sorry if the person he accuseth should be able to clear himself; in short, he is labouring a point which he thinks necessary to his own good; and it would be a disappointment to him, that his neighbour should prove innocent. 5thly, Every good subject is obliged to bear witness against his neighbour, for any action or words, the telling of which would be of advantage to the public, and the concealment dangerous, or of ill example. Of this nature are all plots and conspiracies against the peace of a nation, all disgraceful words against a prince, such as clearly discover a disloyal and rebellious heart: But where our prince and country can possibly receive no damage or disgrace; where no scandal or ill example is given; and our neighbour, it may be, provoked by us, happeneth privately to drop a rash or indiscreet word, which in strictness of law might bring him under trouble, perhaps to his utter undoing; there we are obliged, we ought, to proceed no further than warning and reproof. In describing to you the several kinds of false witnesses, I have made it less necessary to dwell much longer upon this head; because a faithful witness like everything else is known by his contrary: Therefore it would be only a repetition of what I have already said to tell you, that the strictest truth is required in a witness; that he should be wholly free from malice against the person he accuses; that he should not aggravate the smallest circumstance against the criminal, nor conceal the smallest in his favour; and to crown all, though I have hinted it before, that the only cause or motive of his undertaking an office, so subject to censure, and so difficult to perform, should be the safety and service of his prince and country.
