And when those who were close to him heard it, they set out to take custody of him, for they said, “He is out of his mind.” Bible

“those who were close to him.” The Greek is para (#3844 παρά), a preposition usually meaning “beside.” Thus the book of Mark is vague here, saying only that these people were those who were beside him. This is a case when we have to rely on other parallel records to give the details, and we learn what happened from the scope of Scripture. Matthew 12:46 and Luke 8:19 let us know that this group of people is his mother and brothers. This verse is a clear indication that Jesus’ step-father, Joseph, was dead, otherwise he would have been leading the group. That means Joseph died between the time Jesus was 12 (Luke 2:42) and the time he started his ministry. He had worked with his father, the carpenter, and had become a carpenter himself (Mark 6:3). This group “set out” to take him. They arrive in verse 31.
