In Matthew 12, how many other spirits does the returning unclean spirit bring with it?

Answer: Seven

Finding its old house swept clean, the spirit brings seven others more wicked, and the man ends up worse than before.

“Then it goes and brings with it seven other spirits more wicked than itself, and they go in and dwell there. And the final plight of that man is worse than the first. So will it be with this wicked generation.””— Matthew 12:45 (BSB)
