Matthew 12:31-34

Williams(i) 31 So I tell you, every sin and all abusive speech will be forgiven men, but abuse against the Spirit cannot be forgiven. 32 And whoever speaks a word against the Son of Man will be forgiven for it, but whoever speaks abusively against the Holy Spirit will not be forgiven for it, either in this world or in the world to come. 33 "You must either make the tree healthy and its fruits healthy or make the tree sickly and its fruits sickly, for a tree is judged by its fruit. 34 You brood of vipers! How can you, wicked as you are, say anything that is good? For the mouth talks about the things that fill the heart.
