Why did Jesus order the unclean spirits in the Multitude at the Seaside (Mark 3.7-12) to not make him known?

The passage I am referring to is [Mark 3.11-12](https://www.biblegateway.com/passage/?search=Mark+3%3A7-19&version=NRSV) : > 11 Whenever the unclean spirits saw him, they fell down before him and shouted, “You are the Son of God!” 12 But he sternly ordered them not to make him known. I'm confused because why would Jesus not want the multitude of people present with him to not know he is the Son of God? Isn't that what Jesus wanted?
