Matthew 12:31-34 Wherefore I say to you, though every other sin and detraction in men is pardonable, their detraction from the Spirit is unpardonable:

Living_Oracles⁽ⁱ⁾ ³¹ Wherefore I say to you, though every other sin and detraction in men is pardonable, their detraction from the Spirit is unpardonable: ³² for whosoever shall inveigh against the Son of Man may obtain pardon; but whosoever shall speak against the Holy Spirit, shall never be pardoned, either in the present state or the future. ³³ Either call the tree good, and its fruit good; or call the tree bad, and its fruit bad: for we distinguish the tree by its fruit. ³⁴ Offspring of vipers! how can you that are evil speak good things, since it is out of the fullness of the heart that the mouth speaks.
