What is required in the ninth commandment?

That I bear false witness against no man, nor falsify any man's words; that I be no backbiter, nor slanderer; that I do not judge, nor join in condemning any man rashly, or unheard; but that I avoid all sorts of lies and deceit, as the proper works of the devil, unless I would bring down upon me the heavy wrath of God; likewise, that in judgment and all other dealings I love the truth, speak it uprightly and confess it; also that I defend and promote, as much as I am able, the horror and good character of my neighbour.
