In Mark 3, what did those who went out to take custody of Jesus say about him?

Answer: He is out of his mind

When crowds kept Jesus from even eating, those close to him went to take custody of him, saying, "He is out of His mind."

“Then Jesus went home, and once again a crowd gathered, so that He and His disciples could not even eat. When His family heard about this, they went out to take custody of Him, saying, “He is out of His mind.””— Mark 3:20-21 (BSB)
