Matthew 12:31-34 English Standard Version (ESV)

31. Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven.

32. And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.

33. “Either make the tree good and its fruit good, or make the tree bad and its fruit bad, for the tree is known by its fruit.

34. You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks.
