Matthew 12:28-32 New International Version - UK (NIVUK)
28 But if it is by the Spirit of God that I drive out demons, then the kingdom of God has come upon you.
29 ‘Or again, how can anyone enter a strong man’s house and carry off his possessions unless he first ties up the strong man? Then he can plunder his house.
30 ‘Whoever is not with me is against me, and whoever does not gather with me scatters. 31 And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven. 32 Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
