In this Commandment we are to consider, I. What are the duties required? These are, 1. Our endeavouring to promote truth in all we say or do; and that, as to what either concerns ourselves, or others. As to what concerns ourselves, we are to fence against every thing that savours of deceit or hypocrisy; and, in our whole conversation, endeavour to be what we pretend to be; or to speak nothing but what we know, or believe to be true, upon good evidence, the contrary whereunto is lying. As to what concerns others, we must not neglect to reprove sin in them, how much soever our worldly interest may lie at stake. Thus Azariah reproved Uzziah, 2 Chron. xxvi. 18. and Elijah, Ahab; though this could not but be an hazardous attempt in each of them. Moreover, we must endeavour to undeceive others, who are mistaken; especially if the error, they are liable to, be of such a nature, that it endangers the loss of their salvation. We are also to vindicate those who are reproached by others, to the utmost of our power, according as the cause will admit of it. 2. This Commandment obliges us, to endeavour to promote our own, and our neighbour’s good name. (1.) Our own good name; which consists, not in our having the applause of the world, but in our deserving the just esteem thereof, and in our being loved and valued for our usefulness to mankind in general. And this esteem is not to be gained by commending ourselves, or doing any thing, but what we engage in with a good conscience, and the fear of God. And in order hereto, we must, take heed that we do not contract an intimacy with those, whose conversation is a reproach to the gospel, Prov. xxviii. 7. Also we must render good for evil, and not give occasion to those, who watch for our halting, to insult us as to any thing, besides unavoidable infirmities, 1 Pet. ii. 12. Phil. iv. 8.
